MEXICO � MEASURES AFFECTING
TELECOMMUNICATIONS SERVICES

Report of the Panel


(Continued)


B. SECTION 1.1 OF THE REFERENCE PAPER: PREVENTION OF ANTI-COMPETITIVE PRACTICES IN TELECOMMUNICATIONS

4.253 The United States claims that Mexico's ILD Rules operate to prevent competition in the termination of cross-border switched traffic, hold international interconnection rates artificially high, and allow foreign suppliers no choice but to pay Telmex-negotiated rate if they want to supply services on a cross-border basis. According to the United States, Mexico's ILD rules empower Telmex to engage in monopolistic practices with respect to interconnection rates for basic telecom services supplied on a cross-border basis and to create an effective cartel dominated by Telmex to set rates for such interconnection.452 The United States therefore claims that Mexico has failed to honour its commitments under Section 1.1 of the Reference Paper453, which provides that "[a]ppropriate measures shall be maintained for the purpose of preventing suppliers who, alone or together, are a major supplier from engaging in or continuing anti-competitive practices."454

4.254 Mexico replies that its ILD Rules are not subject to the obligations of the Reference Paper, and therefore, cannot be inconsistent with its Section 1.1.455 456 Mexico further points out that, even if its ILD Rules were subject to the obligations of the Reference Paper, the United States, in order to succeed in its claim, must present a prima facie case that Mexico has not maintained "appropriate measures... for the purpose of preventing suppliers who... are major supplier from engaging in or continuing anti-competitive practices". According to Mexico, the United States has not done so.457 Mexico also submits that the United States has misinterpreted the obligations of Section 1.1.458 Mexico also points out that, although its ILD Rules are not subject to the obligations of the Reference Paper, it has maintained appropriate measures for the purpose of preventing Telmex from engaging in anti-competitive practices.459 According to Mexico its measures meet the standards of Section 1.1 of the Reference Paper and the Mexican regulatory framework contains the requisite of "Competitive Safeguards".460

1. Panel's standard of review

4.255 Mexico submits that the fact that the United States may have different goals centered on promoting the interest of its own carriers should not influence the manner in which the Panel interprets Section 1 in the light of the objectives of the GATS, which include:

"Desiring the early achievement of progressively higher levels of liberalization in trade in services � while giving due respect to national policy objectives;

Recognizing the right of Members to regulate � the supply of services within their territories in order to meet national policy objectives and, given wide asymmetries existing with respect to the degree of development of services regulations in different countries, the particular need of developing countries to exercise this right;

Desiring to facilitate the increasing participation of developing countries in trade in services and the expansion of their service exports including, inter alia, through the strengthening of their domestic services capacity and its efficiency and competitiveness �"461

4.256 Mexico also submits that Section 1.1 does not require a Panel to act as a domestic anti-trust authority, as, Mexico indicates, the United States implicitly argues. In Mexico's view, Section 1.1 sets out "principles and definitions" for regulatory authorities and does not mean that a single and common regulatory system should be imposed in the territory of all WTO Members.462

2. Section 1.1 of Mexico's Reference Paper

(a) Purpose of Section 1.1

4.257 According to the United States, Section 1.1 of Mexico's Reference Paper provides for the maintenance of appropriate measures to prevent major suppliers from engaging in or continuing anti-competitive practices.463 The United States recalls that those appropriate measures are intended to prevent anti-competitive conduct by suppliers who "alone or together" are a major supplier. The United Sates submits that the "or together" language in Section 1.1 indicates that the negotiators attached relevance to horizontal coordination between suppliers. The United States also points out that, although this phrase has direct relevance to the definition of "major supplier," it also lends context to the interpretation of the term "anti-competitive practices," which the United States contends includes, at the very least, horizontal price-fixing agreements.464

4.258 According to Mexico, the obligation in Section 1.1 is to maintain "suitable or proper" measures with the object or the intention of preventing Telmex from engaging in anti-competitive practices.465 Mexico claims that Section 1.1 is drafted in such manner that it allows Mexico a large measure of discretion in deciding what measures would be suitable or proper to accomplish the intended objectives and cannot be interpreted to mean that Mexico is required to prevent all suppliers from even engaging in or continuing anti-competitive practices, as suggested by the United States.466 Mexico further submits that, Section 1.1 creates an obligation of means, not an obligation of result.467

(b) Extent of the requirement under Section 1.1

4.259 Mexico maintains that Section 1 of the Reference Paper does not require markets to be opened to competition. According to Mexico, the opening of markets is a market access issue that is dealt with in Mexico's Schedule of Specific Commitments. Mexico submits that Section 1 requires only that appropriate measures be maintained for the purpose of preventing major suppliers from engaging in or continuing anti-competitive practices.468

4.260 The United States submits that it is not arguing that Section 1 requires a guaranteed result and agrees that it is the maintenance of appropriate measures that is required.469 According to the United States, what matters is that a Party maintain measures of some sort to prevent, not stimulate or condone, anti‑competitive marketplace conduct.470 The United States further submits that it does not claim that Section 1 of the Reference Paper contains language requiring a market to be opened to competition or that the requirement of the Reference Paper can only be met by opening a market to competition. According to the United States, Mexico's obligation to open various markets derives from the broad range of market access commitments on basic telecommunications contained in its Schedule.471

(i) "Appropriate measures"

aa) Whether the ILD Rules are "appropriate measures" under Section 1.1

4.261 The United States asserts that the FCC has identified Rule 13 as restricting competition, limiting the ability to achieve cost-based cross-border interconnection rates.472 According to the United States, Rules 13 and 23 prevent Mexican and foreign suppliers from agreeing to alternative rates that could exert competitive pressures on the rate exclusively negotiated by Telmex.473 The United States submits that Mexico's ILD Rules are the opposite of "appropriate" measures to prevent anti-competitive practices, as required by Section 1.1 of the Reference Paper.474

4.262 Mexico contends that Section 1.1 does not require Mexico to ensure that Telmex does not act in an anti-competitive manner. Mexico submits that it is obliged to put in place "appropriate measures" aimed at preventing anti-competitive practices475 and that it has maintained appropriate measures for the purpose of preventing Telmex from engaging in anti-competitive practices.476 According to Mexico, it must be recognized that the ILD Rules pursue legitimate policy development objectives, and, in fact, constitute appropriate measures to encourage and ensure competition among domestic long-distance carriers.477 In Mexico's view, the United States' claim under Section 1 fails, even under its incorrect interpretation of the obligation in Section 1.1, since the ILD rules do not require anti-competitive practices.478

4.263 Mexico submits that Rule 13 grants to the largest carrier of outgoing international traffic to a particular country the right to negotiate the rate for terminating incoming international calls from that country. Mexico indicates that the uniform settlement rate policy ensures that all Mexican international service providers that terminate international calls are paid the same negotiated rate. Mexico further points out that the proportional return policy, ensures that each Mexican provider receives fees proportionate to the number of calls it actually handles.479 According to Mexico, the combination of these policies prevents a large carrier taking advantage of that authority by retaining an unfair share of the revenue from incoming international traffic, or otherwise undercutting new entrants.480

4.264 According to the United States, preventing price competition by new entrants to protect a major supplier's high price cannot possibly be understood as promoting competition.481 The United States submits that Mexico has offered no evidence that the new entrant carriers at issue need to be protected from a competitive market or from Telmex. In its view, their best prospects of building market share and challenging Telmex�s dominance in fact lie in the freedom to compete with Telmex. The United States argues that Mexico�s general competition law and its competition authority, the CFC, can address any attempts by Telmex, alone or in collusion with others, to engage in exclusionary or predatory conduct, once the constraints of the ILD rules are lifted.482 The United States argues that although Mexico maintains a general competition statute, it also maintains measures that require its telecommunications carriers to adhere to a Telmex-led horizontal price-fixing cartel, restrict competition for the termination of international switched telecommunications traffic and otherwise restrict the supply of scheduled telecommunications services.483 The United States claims that these measures stifle market challengers and allow Telmex to maintain artificially high prices.484

4.265 The United States recalls Mexico's report to the OECD's Committee on Competition Law and Policy in which Mexico stated that its own ILD Rules may not be the most favourable for competition.485 The United States claims Telmex is exactly the sort of former official monopoly that the Reference Paper meant to be restrained in order to allow a competitive basic telecom services trade to develop.486 The United States also claims that the OECD's Report on Regulatory Reform in Mexico has recognized that Mexico's ILD Rules prevent competition in the termination of international traffic and prevents prices from decreasing for consumers, to the benefit of the Mexican telecommunications operators. The United States further points out that the OECD Secretariat concluded that an immediate price reduction on international calls would follow the elimination of the Mexican system.487

4.266 Mexico submits that its ILD Rules are not per se anti-competitive, they just form part of Mexico's regulatory framework, which is aimed at increasing competition in its domestic telecommunications market.488 Mexico claims that Rule 13 of the ILD in combination with its uniform settlement policy and the requirements of proportional return, serves to preserve competition among domestic carriers and to promote investment in the domestic telecommunications infrastructure, and cannot be evaluated in isolation.489

4.267 The United States considers that Mexican ILD Rules, which contain an explicit restriction on price competition together with the division of supply among market participants, have the classic features of a cartel. The United States says that Mexico admits that the effect of its ILD Rules is to prevent smaller carriers from undercutting Telmex on price.490 The United States submits that ILD Rule 13, in combination with other provisions of the ILD rules, affirmatively requires and promotes per se anti-competitive conduct. According to the United States, the effect of Mexico's rules is to maintain rates for international interconnection that are well in excess of cost, eliminating any competitive incentive to lower international interconnection rates. The United States further points out that the reduction of international interconnection rates, as have occurred, cannot be attributed to this anti-competitive scheme.491

4.268 According to the United States, the impact of ILD Rule 13 is to prevent new entrant international carriers in Mexico, some of which are affiliated with United States or other foreign providers, from undercutting the above‑cost prices charged by Telmex, thereby attracting more traffic for themselves. The United States claims that Mexico has acknowledged its concern about new entrant carriers engaging in a "price war" with Telmex.492 The United States submits that Mexico's maintenance of ILD Rule 13, in other words, is not directed at preventing harm to competition but rather is directed at preventing the natural results of competition. The United States further points out that Mexico prohibits price competition in the market for interconnection provided to United States suppliers operating on a cross‑border basis, and justifies this prohibition as necessary to prevent such competition from reducing rates. In the United States' view, this can only be regarded as anti‑competitive.493

4.269 Mexico alleges that its ILD rules governing settlement rates and proportionate return are not only appropriate, but necessary to prevent a major supplier from engaging in anti-competitive practices in the Mexican domestic market for long-distance services, and to promote the development of the nation's telecommunications infrastructure to meet fundamental goals such as broader consumer access to service.494 According to Mexico, the requirements for uniform settlement rates and proportionate return in ILD Rule 13 are crucial: (i) to preserve competition in Mexico's domestic market for long-distance services; and (ii) to promote infrastructure development by ensuring that carriers' shares of the settlement rate revenue from incoming calls are proportionate to their success in penetrating the domestic market for outgoing international calls. This is why, in Mexico's view, the ILD rules must be evaluated in their totality.495

4.270 The United States submits that its concern that Telmex is engaging in anti-competitive behaviour in its accounting rate negotiations with United States carriers is exacerbated by the fact that, under Rule 13 of the regulations issued by Mexico's Secretariat of Communications and Transport, Telmex negotiates accounting rates for all Mexican carriers.496 As a result, the United States contends, Telmex has de jure monopoly power in its negotiations with United States carriers. The United States submits that its suppliers have no choice but to interconnect with the Mexican public network at the border, since under Mexico's ILD Rule 3, only "international port operators" may interconnect with the public networks of foreign operators. The United States recalls that Mexican law permits only Mexican facilities-based operators to hold a concession to supply long-distance services.497 The United States further points out that Mexico leaves no choice but to pay the Telmex-negotiated interconnection rates, to suppliers from the United States willing to provide scheduled services on a cross-border basis. The United States claims that Mexico does not allow "resale" which requires the use of private lease circuits for the purpose of providing circuit switched telecommunication traffic.498

4.271 Mexico argues that the United States' arguments are an attempt to force Mexico to permit ISR.499  According to Mexico, its commitments were limited to allow international traffic only "through the facilities of an enterprise that has a concession granted by the Secretar�a de Comunicaciones y Transportes". Mexico argues that Section 1.1 cannot be construed to indirectly grant carriers, from the United States, access to ISR when Mexico has an express limitation that allows it to prohibit ISR.500 According to Mexico, the end result of the United States approach would be to affect competitive long-distance carriers in Mexico and thereby cut down domestic market competition with the argument of reducing costs for AT&T and Worldcom. It further argues that the United States, incidentally, has not offered any information whatsoever on how elimination of the ILD Rules would promote competition in the United States, where WorldCom and AT&T together control more than 90 per cent of United States traffic to Mexico. In its view, even with Rule 13, the negotiating power of the duopsony (exclusive market power of two buyers on a market) on the United States side has been so dominant, and the volume of traffic southwards so great, that historically the settlement rate has been drastically reduced.501

4.272 In response to a question by the Panel, Mexico indicated that it is not aware of any other WTO Member that has a de jure Rule 13. However, it argues, most Members, including the United States, have a de facto Rule 13, since the carrier with the highest market share is the one that negotiates the corresponding accounting rates (and therefore the settlement rates) with its counterpart, which also has the highest corresponding market share, and the remaining carriers on both sides follow their leaders. Mexico explains that, in the United States, for example, the ISP establishes uniform settlement rates and proportional return rules that result in a de facto Rule 13 for all United States carriers. However, if one of the economic effects of Rule 13 could be said to prove "anti-competitive", most, if not all, WTO Members have regulatory measures producing that effect. As is the case with ILD Rule 13, there are legitimate grounds for such measures and the measures should not be prohibited simply because one of the effects might be "anti-competitive" according to a particular criterion or measure.502

4.273 The United States submits that Mexico finally admits that no other WTO Member maintains a measure similar to Rule 13, and fails to identify any WTO Members, other than purportedly the United States, which it claims "have a de facto Rule 13." The United States submits that Mexico then repeats its false charges that United States rules and policies are similar to those of Mexico, and again makes no attempt to rebut the evidence put forward by the United States showing that the United States International Settlements Policy requires nondiscriminatory rather than uniform rates, that ISP non-discrimination and proportionate requirements apply only to arrangements with dominant carriers that maintain high rates, and that all United States carriers negotiate rates independently.503

bb) Whether a proportionate return system could be an anti-competitive measure

4.274 Mexico claims that Rule 13 prevents international anti-competitive activities. According to Mexico, the United States fails to mention that the two other major Mexican long distance carriers are affiliates of carriers from the United States and also fails to explain how allowing those carriers to dictate rates to their Mexican affiliates would serve any anti-competitive purpose. Mexico submits that its ILD Rules were adopted to mirror those of the United States, which otherwise would give carriers from the United States an unbalanced negotiating advantage over Mexican carriers.504 Mexico contends that its rules have prevented large foreign carriers from pressuring their own affiliated Mexican companies to agree to predatory, uneconomic prices that would serve only the interest of companies from the United States to the detriment of the Mexican market, undermining the opportunity to expand access to basic telecommunications services to those who now lack such services, and who comprise two-thirds of Mexican households.505

4.275 The United States replies that its international regulatory scheme upon which Mexico's ILD Rules were allegedly based is qualitatively different from Mexico's rules. According to the United States, its rules are designed to prevent monopolistic abuses where the potential for them still exists, not to authorize and mandate such abuses like Mexico's ILD Rules. According to the United States its uniform or nondiscriminatory settlement rate and proportionate return requirements only apply to foreign carriers with market power, whereas Mexico's rules apply to all foreign carriers regardless of their market power. The United States claims that its rules encourage all its carriers to negotiate cost-oriented rates. The United States further points out that Mexico's rules prohibit all carriers, except Telmex, from negotiating rates and thus encourage artificially high rates, the exact opposite of cost-based.506 The United States submits that it has not at any time given one carrier the exclusive authority to negotiate international interconnection rates for itself and other competitive carriers.507

4.276 Mexico contends that, despite the United States claim that it applies its International Settlements Policy in a narrowly targeted fashion, it has waived the policy only for 15 countries, and it deems virtually every major foreign carrier to have market power, including all local exchange carriers in the countries to which the Policy applies.508

4.277 In the United States' view, the use of a proportionate return system is not an anti-competitive practice where it is used solely to prevent the abuse of market power. The United States claims that it applies proportionate return requirements only to cross border suppliers that both (1) possess market power at the foreign end of the international route, and (2) maintain high settlement rates.509 According to the United States, proportionate return is applied to dominant suppliers with high rates in order to prevent those dominant suppliers from using their control of return traffic to obtain additional concessions from competing suppliers in the United States. The United States claims that, except for dominant suppliers with high rates, cross-border suppliers into the United States are not subject to proportionate return. The United States refers that all suppliers, from all countries, that do not possess market power at the foreign end of the relevant international route, including all Mexican suppliers except Telmex, are not subject to proportionate return, and may terminate unlimited amounts of bound traffic in the Unite States with any supplier.510

4.278 The United States claims that it is pro-competitive rather than anti-competitive to apply a proportionate return system narrowly in order to prevent dominant suppliers with high settlement rates from using their market power to receive increased above-cost subsidies. The United States points out that Mexico has established a "proportional return" system under which Mexican carriers receive a share of the above cost payments associated with inbound international traffic in relation to their outbound international traffic.511 In the Unites States' view, Mexico does not apply proportionate return to prevent the abuse of market power, but just requires all suppliers to comply with proportionate return, irrespective of whether they possess market power. The United States submits that Mexico's proportionate return requirement operates "in combination with" the Telmex monopoly on rate negotiations and the requirement for uniform rates to prevent one Mexican supplier "undercutting" any other Mexican supplier, or otherwise competing to increase its share of traffic received from cross-border suppliers from the United States.512 The United States contends that Mexico applies proportionate return broadly to all suppliers with the purpose of maintaining payment of above-cost subsidies resulting from the abuse of market power by Telmex.513

4.279 The United States submits that Mexico has failed to explain why a Mexican carrier, even if minority owned (but not controlled) by a United States. carrier, would ignore its responsibility to its majority shareholders and agree to predatory, uneconomic prices for international interconnection. In its view, the impact of ILD Rule 13 is to prevent new entrant international carriers in Mexico, some of which are affiliated with United States or other foreign providers, from undercutting the above‑cost prices charged by Telmex, thereby attracting more traffic for themselves. Mexico has acknowledged its concern about new entrant carriers engaging in a "price war" with Telmex. Mexico�s maintenance of ILD Rule 13, in other words, is not directed at preventing harm to competition but rather is directed at preventing the natural results of competition. Mexico prohibits price competition in the market for interconnection provided to United States suppliers operating on a cross‑border basis, and justifies this prohibition as necessary to prevent such competition from reducing rates. This can only be regarded as anti‑competitive.514

4.280 In Mexico's view, the proportional return system is a pro-competitive practice, directed at Mexico's legitimate policy objectives.515 According to Mexico, its ILD Rules promote competition in the Mexican domestic market, while protecting Mexican carriers from being played off each other by foreign carriers. Mexico submits that among other pro-competitive features, ILD Rules prevent negotiation by one supplier of a settlement rate that could undercut other suppliers because it would be unprofitable for them (i.e., a predatory settlement rate). Mexico points out that the United States tries to dismiss the pro-competitive goals of the ILD rules as irrelevant, persisting in its claim that Mexico's Reference Paper requires competition in the negotiation of accounting rates regardless of the negative impact on competition that this would bring to the domestic market, including the impact on international calling services to consumers.516

(ii) "Major supplier"

4.281 The United States explains that Mexico's ILD Rule 13 provides that the carrier with the greatest share of outgoing international calls in the last six months is given the exclusive authority to negotiate the interconnection rates with foreign carriers. The United States points out that Telmex has always been the carrier with the largest outgoing international calls, holding the exclusive negotiating authority. The United States further points out that ILD Rules require all Mexican long-distance basic telecom suppliers to charge foreign suppliers only the Telmex-negotiated cross-border interconnection rate, even if Telmex is not a party to that agreement.517 The United States therefore contends that Mexico's rules empower and require Telmex to operate a cartel dominated by itself to fix rates for international interconnection and mandate that all Mexican carriers must adhere to those rates.518

4.282 The United States submits that Section 1.2 of the Reference Paper defines "major supplier" as a "supplier which has the ability to materially affect the terms of participation (having regard to price and supply) in the relevant market519 for basic telecommunications services as a result of: (a) control over essential facilities; or (b) use of its position in the market."520 According to the United States, Telmex satisfies this definition of "major supplier" because it has the ability, in the Mexican market, to use its position to materially affect the prices charged and the supply of services.521 The United States further submits that Mexican competition law, in determining whether an economic agent has "substantial power in the relevant market", considers "the possibility to fix prices unilaterally or to restrict supply in the relevant market, without competitive agents being able, presently or potentially to offset such power", and other factors including "existence of entry barriers", existence and power of � competitors", and possibility of access � for sources of inputs.522 The United States defines the relevant market as the termination of voice telephony, facsimile and circuit‑switched data transmission services supplied on a cross‑border (i.e., international) basis from the United States into Mexico, which, in its view, is demonstrated by well‑accepted principles of market analysis which derive from competition law.523 The United States recalls that Mexican competition law provides that in order to determine a relevant market, it is necessary to evaluate "[t]he possibilities of substituting the goods or services in question, with others of domestic or foreign origin, considering technological possibilities, and the extent to which substitutes are available to consumers and the time required for such substitution".524

4.283 Mexico argues that the United States has not demonstrated that the interconnection at issue concerns a "major supplier"525 and has not presented a prima facie case that Telmex is a "major supplier" within the meaning of the Reference Paper.526 In Mexico's view, the United States' analysis527 in which it sets out its argument that Telmex is a "major supplier" is flawed.528 In this regard, Mexico submits that the United States has failed to clearly define the services at issue and how they are supplied.529 It further contends that, even if assuming that the services at issue are the transportation and transmission of telecommunications signals and that the mode of supply at issue is mode 1 (cross-border), the United States has failed to explain how the "relevant market" it defines is relevant to the cross-border supply of such services.

4.284 As regards the United States' definition of "relevant market" as "the termination of voice telephony, facsimile and circuit-switched data transmission services", Mexico submits that "termination services", to the extent that they are provided by a carrier in a WTO Member, are provided on a mode 3 (commercial presence) basis and not on a cross-border basis. Mexico claims that the United States' analysis confuses two distinct modes of supply, cross-border and commercial presence. Mexico further claims that the United States relies on a relevant market resolution by the Mexican competition authority that is under review by Mexican courts precisely because the data it was based upon.530 Mexico also argues that, assuming that defining the relevant market as "termination services" is relevant, it is unclear whether a carrier in Mexico, such as Telmex, is providing "termination services" in the light of the technical distinction between the traditional accounting rate procedure and a termination regime. It further argues that, even if a carrier in Mexico does provide termination services for foreign carriers wishing to terminate calls within Mexico, "termination services" and how to schedule those services was a specific topic of discussion during the negotiations on basic telecommunications. There was no agreement on these services and, even if there was, Mexico has not inscribed in its Schedule any specific commitments with respect to these services, for example, by using the approach proposed by Australia during the negotiations.531

4.285 The United States responds that Mexico's assertion that termination services are not interconnection is refuted by the plain language in Section 2.1 of Mexico's Reference Paper definition of "interconnection". Additionally, the United States submits that the European Commission has described call termination as "the most basic interconnection service provided" and that in its submissions during the negotiations, Australia stated that termination of international traffic is interconnection, and there is no indication that any other Member objected to this characterization.532

4.286 Mexico submits that, basically, Mexico and the United States differ on what constitutes the relevant market in which competition must be promoted and protected. Mexican policy, as shown by the ILD Rules, is that domestic carriers should share in and split agreements for incoming calls in terms of their success in securing a share on the domestic market and generating outbound calls. The United States sees it differently (apparently, solely for the purposes of its argument in this case), i.e. the only "market" worth protecting is the one for terminating United States traffic to Mexico. Mexico contends that the United States is acting as if new operators should compete to carry incoming international traffic calls instead of competing for end-customers in Mexico. According to the criterion set by the United States, it argues, an operator who has made a minimal investment in Mexican infrastructure should be allowed to do so on an unlimited basis, taking all the revenue for international calls from the operators who have made such investments and have obtained successful results in acquiring a share of the market.533

4.287 The United States claims that Mexico is attempting to justify its anti-competitive ILD rules by alleging that the United States "is acting as if new operators should compete in order to carry incoming international traffic calls instead of competing for end-customers in Mexico." The United States submits that Mexico misstates the United States position. In the view of the United States, Mexico�s WTO obligations require it to allow new carriers to compete both to carry inbound international calls and for customers in Mexico. Likewise, it argues, Mexico implies that it is wrong for the United States to assert that carriers that have made "minimal" investments in Mexican infrastructure should be allowed to engage in "unlimited" competition. The United States maintains that a carrier�s ability to compete, either for inbound international calls, Mexican customers or in any other area, is limited only by the limitations, if any, in Mexico�s Schedule. Mexico cites no requirement in its Schedule that links a supplier�s ability to compete for inbound international calls to that supplier�s level of investment in Mexican facilities. Additionally, Mexico does not restrict competition for inbound international traffic merely for those suppliers with an undefined level of "minimal investment." Instead, Mexico's ILD rules restrict competition for inbound international traffic for all commercially present suppliers, irrespective of their level of investment in Mexican facilities.534

(iii) "Anti-competitive practices"

aa) Definition of anti-competitive practices

4.288 The United States explains that apart from three illustrative practices included in Section 1, the Reference Paper does not define the term "anti-competitive practices". The United States considers that this term encompasses, at a minimum, what are usually characterized as "abuses of dominant position" and/or "monopolization" offences as well as "cartelization", which, according to the United States, are common antitrust concepts generally included within the universe of business practices usually found to be anti-competitive under national regulatory schemes and competition laws and policies. The United States claims that Mexico's antitrust law generally prohibits behaviour of this sort.535 The United States further indicates that the 1999 Report of the WTO Working Group on the Interaction Between Trade and Competition Policy describes the nature and consequences of "horizontal" agreements which are likely to have a direct, negative impact on competition and to give rise to the exercise of market power.536

4.289 Mexico indicates that a definition of "anti-competitive practices" is provided in Section 1.2, which states that:

"The anti-competitive practices referred to in the above paragraph shall include in particular:

(a) Engaging in anti-competitive cross-subsidization;

(b) using information obtained from competitors with anti-competitive results; and

(c) not making available to other services suppliers on a timely basis technical information about essential facilities and commercially relevant information which are necessary for them to provide service." (emphasis added)537

4.290 Mexico argues that the term "shall include" indicates that the list is non-exhaustive and that the addition of the words "in particular" demonstrate a focus on certain types of activities � namely, actions taken by private companies to gain an advantage over their competitors. Mexico claims that carriers from the United States are not competing with Mexican carriers when they enter into bilateral accounting rate arrangements since they do not offer service to Mexican customers. Mexico submits that, even if the legal requirement that all Mexican carriers charge the same settlement rate somehow could be construed as a "horizontal price fixing agreement" by private companies, such an agreement would not be encompassed by Section 1 because all Mexican carriers would be participating in the conspiracy and none would be harmed by it.538

bb) Government intervention

4.291 According to the United States, the fact that anti-competitive conduct is compelled by the government does not change the underlying nature of the conduct as anti-competitive.539 In its view, even if an activity engaged in by Mexico's major supplier, Telmex, is immunised from domestic enforcement action under Mexican law, or is in some sense the act of the Mexican State itself, that does not alter the anti-competitive character of the activity at issue. The United States notes that it is Mexico's failure to observe the obligations of Section 1 that is at issue in this dispute, not Telmex 's failure to observe those obligations. According to the United States, if a WTO Member were able to immunize itself from the obligation incumbent upon it under Section 1 to take measures to prevent anti-competitive conduct by major suppliers by simply requiring anti-competitive conduct by major suppliers, the entire purpose of Section 1 would be undermined. The United States says that such an interpretation of Section 1 would encourage Members affirmatively to maintain measures requiring anti-competitive conduct, rather than put in place measures to prevent anti-competitive conduct.540

4.292 Mexico submits that the United States has failed to establish that Section 1 disciplines regulatory "measures" of a WTO Member that have an anti-competitive effect.541 In Mexico's view, "anti-competitive practices" refer to the practices of a major supplier and not to governmental measures that may have an anti-competitive effect.542 Mexico recognizes that all regulation of economic activity, by definition, interferes with the operation of a freely competitive marketplace, including rate-setting by governmental authorities, but claims that such government regulation itself is not typically understood to be capable of violating competition rules.543 According to Mexico, if the United States' interpretation is to be accepted, all government regulatory measures in the telecommunications sector that restrain the actions of a major supplier in a manner that interferes with the operation of a freely competitive marketplace would be prohibited. Mexico claims that this is not what was intended by Section 1 of its Reference Paper. Mexico submits that there is no basis in the text of Section 1 to judge the legitimacy of a WTO Member's internal regulatory policies in circumstances where no multilaterally agreed-upon benchmarks exist. Mexico further contends that in order to justify its own anti-competitive measures, the United States essentially distinguishes between anti-competitive measures that, in its view, have legitimate policy objectives and those that, in its view, do not. In Mexico's view, if the drafters of Section 1 meant to include government regulatory measures, surely they would have included text to take into account such important distinctions and to provide objective benchmarks for assessing the legitimacy of such measures.544

cc) Price fixing as an anti-competitive practice

4.293 Answering a Panel's question545, the United States submits that, if price-fixing is anti-competitive, then it is anti-competitive even if required by law. According to the United States, even if an activity engaged in by Mexico's major supplier, Telmex, is immunized from domestic enforcement action under Mexican law, or is in some sense the act of the Mexican state itself, that does not alter the anti-competitive character of the activity at issue.546 The United States further submits that Telmex's ability to negotiate uniform settlement rates is per se anti-competitive. In its view, this is, by definition, a horizontal price-fixing cartel that fits within virtually any definition of anti-competitive practice. The United States notes that horizontal price fixing is condemned both as a per se violation of its own law under Section 1 of the Sherman Act and as an absolute monopolistic practice under Article 9 of Mexico's FLEC.547 The United States affirms that it is the setting of the rate by a monopolist (since Telmex is given the exclusive authority, it is acting as a monopolist in this context) and the use of this rate by all other suppliers (horizontal price-fixing) that comprise the anti-competitive practices that form the basis for the United States' claim under Section 1 of the Reference Paper. It submits that the fact that the government requires the anti-competitive practice does not change the nature of the practice as anti-competitive.548

4.294 Also in answer to a Panel's question, Mexico submits that the fixing of a uniform price cannot be an anti-competitive practice in violation of the obligations under the Reference Paper if uniform prices are required by law.549 Mexico further submits that Telmex's ability to negotiate uniform settlement rates is not per se anti-competitive since Mexican law does not give Telmex the authority to negotiate the rate. According to Mexico, Rule 13 provides the carrier having the greatest share of outgoing traffic to a particular country is authorized to negotiate the rate. Mexico claims that new entrant carriers have been gaining important shares of outgoing traffic on certain routes, and therefore may soon have the right to negotiate the rates for those routes.550

4.295 Mexico further submits that, in the economic sense, monopolies may be "anti-competitive". However, it cannot be said that a domestic regulatory regime that establishes and permits a monopoly or small number of exclusive service suppliers to exist is equivalent to requiring an "anti-competitive practice" within the meaning of Section 1 of Mexico's Reference Paper. GATS Article VIII explicitly contemplates that WTO Members can maintain monopolies and exclusive service suppliers. Moreover, many WTO Members who have inscribed a Reference Paper maintain monopolies or exclusive service suppliers under their domestic law. Section 1 of Mexico's Reference Paper and the equivalent provisions in the Reference Papers of other WTO Members cannot be interpreted to nullify a right that exists under GATS Article VIII. Mexico submits that the obligations in the Reference Paper were negotiated specifically to prevent major carriers in regulated markets from abusing their market positions by engaging in anti-competitive "private" actions. With respect to "the use of the [Telmex] rate by all other suppliers", such action is not the result of anti-competitive practices of a major supplier � the focus of Section 1 of Mexico's Reference Paper � rather, it is the result of a legitimate government regulatory scheme.551

4.296 The United States responds that there is no basis for Mexico's assertion that GATS Article VIII contemplates Mexico's restrictions on competition through the ILD rules, and therefore somehow precludes any challenge to such measures under Article 1 of the Reference Paper.552 Article VIII only applies to monopolists and "exclusive service suppliers, where a Member, formally or in effect, (a) authorizes or establishes a small number of suppliers and (b) substantially prevents competition among those suppliers in its territory." Mexico has placed no limitation on the number of concessionaires, either formally or in effect, and Article VIII therefore does not apply. Mexico's Schedule contains no Article XVI:2(a) limitation on the number of service suppliers, and as of September 2002 Mexico had granted no fewer than 27 concessions for domestic long-distance service, 11 of which are authorized to operate international ports.553

(c) Relationship between Section 1.1 and Section 2.2(b) of the Reference Paper

4.297 The United States submits that a Member that scheduled the Reference Paper as an additional commitment is required by Section 1 of the Reference Paper to maintain appropriate measures to prevent its major supplier from engaging in or continuing anti-competitive practices, and is also obliged under Section 2.2(b) to ensure interconnection with that major suppliers on reasonable terms, conditions and rates. The United States considers that depending on the facts at issue, a conduct could be both anti-competitive and restrict the supply of basic telecommunication services, leading to a violation of both Sections 1 and 2.2(b).554 The United States also submits that the purpose of Section 1 of the Reference Paper is to support the parallel goals of de-monopolization and market access by protecting and fostering competition among basic telecom competitors, and that it complements the more specific interconnection rules for major suppliers found in Section 2.555

4.298 Mexico submits that Sections 1 and 2 of Mexico's Reference paper do not cover the same subject matter. In Mexico's view, independent meaning must be given to each provision and overlapping interpretations must be avoided.556 According to Mexico, what is "not reasonable" under Section 2.2 and what is "anti-competitive" under Section 1.1 are measured against different standards, there being no relationship between the two.557

(d) Relationship between Sections 1.1 and 3 of Mexico's Reference Paper

4.299 In response to question No. 23(b) of the Panel meeting of 13 March 2003558, Mexico explains that there is no legal relationship between Sections 1.1 and 3 of its Reference Paper. According to Mexico, those Sections relate to different subjects and lay down different obligations. Mexico submits that Section 3 has not been the subject of this dispute. In Mexico's view, Section 1.1 does not regulate measures by a Member with a side-effect that may prove anti-competitive from a particular standpoint. Mexico contends that Section 3 relates to the maintenance of a type of specific governmental measure for the universal service obligation, which includes laying down obligations on domestic carriers to provide universal service coverage over a Member's territory and that such measure be, inter alia, administered in a "transparent, non-discriminatory and competitively neutral" manner.

4.300 Mexico submits that, for the purposes of this dispute, it is notable that when a governmental measure must be regulated in accordance with Mexico's Reference Paper, it is done explicitly as in Section 3, so that it identifies the exact governmental measure in question (i.e. a "universal service" measure and not a general governmental regulatory measure, which would be the outcome of the United States interpretation of Section 1.1 of Mexico's Reference Paper) and the specific disciplines that apply (i.e., "competitively neutral", contrary to "anti-competitive practices", which are more subjective and general). According to Mexico, this confirms its position that Section 1.1 of its Reference Paper does not regulate a Member's measures, but the "practices" of a "major supplier".559

4.301 The United States replies noting that Mexico's ILD Rules are not "legislative requirement[s]," but regulatory requirements imposed by Cofetel. According to the United States, Mexico's ILD Rules 13 and 23 implement per se anti-competitive practices under Section 1.1 of the Reference Paper, which are not mitigated by any application of Section 3.560

4.302 The United States submits that Section 3 allows a Member to "define the kind of universal service obligation it wishes to maintain". The United States claims it is aware of no universal service obligation implemented or defined by the Mexican authorities, and no such obligation is defined by the ILD rules. The United States further submits that Mexico has not even identified or defined a universal service obligation that would, were it identified or defined, "not be regarded as anti‑competitive per se," pursuant to Section 3. In the United States view, since Mexico has not identified or defined a universal service obligation, it is not entitled to the presumption against per‑se anti‑competitiveness included in Section 3.561

4.303 The United States further submits that even if Mexico had defined a universal service obligation and Section 3 were to apply, Mexico would not be entitled to this presumption, since its ILD rules also breach the additional requirements that the defined obligation be "administered in a transparent, non‑discriminatory and competitively neutral manner and not [be] more burdensome than necessary for the kind of universal service defined by the Member."562 Specifically, the United States argues that, at present, any alleged universal service obligations levied against foreign suppliers are apparently hidden in interconnection rates paid to Telmex. There is no transparency when universal service obligations are hidden in interconnection rates paid to the major supplier. The United States submits that a transparent process must, at a minimum, identify the level of charges associated with the universal service obligation. The ILD rules also fail to provide the "non‑discriminatory and competitively neutral" administration of the defined universal service obligation that is required by Section 3. Because the ILD rules only address interconnection rates paid by cross‑border suppliers, they ensure that the entire burden of any universal service obligation implemented in this way falls upon cross‑border suppliers. Finally, the United States notes that the ILD rules fail to identify the monetary level of the obligation and ensure that the charges are commensurate with that obligation. Because Mexico has not defined a universal service obligation, it cannot determine what level of charges would be "necessary" to meet that obligation. Similarly, levying charges allegedly associated with that obligation are by definition more burdensome than necessary.563

C. SECTION 5 OF THE GATS ANNEX ON TELECOMMUNICATIONS

4.304 The United States claims that Mexico has failed to honour its commitments under the GATS Annex on Telecommunications. According to the United States, the Annex requires Mexico to ensure that service suppliers of other Members can access and use public telecommunications transport networks and services on reasonable and non‑discriminatory terms and conditions to provide a scheduled service.564 In the United States' view, Mexico has not fulfilled its obligations under either Section 5(a) or 5(b) of the Annex for the provision of the scheduled services.565

4.305 Mexico submits that the scheduled services - i.e. the market-access commitments - that the United States alleges that Mexico has made and which are the basis for the claim under the Annex do not exist. In Mexico's view, the United States is incorrectly arguing that the Annex confers rights to supply basic telecommunications services when the Annex applies only to access to and use of those services. Therefore, Mexico submits that the provisions of the Annex cited by the United States566 do not apply to the facts of this dispute. Mexico further submits that even if Sections 5(a) and 5(b) applied, the United States has failed to present a prima facie case that these provisions have been violated. According to Mexico, the measures the United States is challenging are consistent with paragraphs 5(e), 5(f) and 5(g) of the Annex.567

1. Application of the Annex

4.306 The United States submits that the GATS Annex on Telecommunications addresses telecommunications as a means of transporting scheduled services. In its view, the Annex requires Members to ensure that users of telecommunications (e.g., service suppliers) have access to, or use of, telecommunications � free from obstacles � to deliver their services.568 It further submits that the Annex grew out of a recognition that telecommunications represent the primary delivery mechanism for many services, particularly those offered on a cross‑border basis. Without telecommunications, it would be impossible for many service suppliers to deliver their services.569 The United States claims that access to telecommunications as a transport mechanism depends on those entities which control telecommunications networks and offer telecommunications services. Such entities � principally monopolies or former monopoly providers � have represented the principal obstacle to access and use of telecommunications as a transport mechanism.570 Like the Reference Paper, the Annex represents an effort to prevent dominant telecom providers from using their control over public telecom networks and services to undermine the supply of a scheduled service and to ensure that dominant telecom suppliers cannot nullify the services commitments that their home country undertakes.571

4.307 Mexico contends that enhanced services and suppliers of services in sectors other than the telecommunications sector rely on "access to and use of" the existing public telecommunication network. According to Mexico, the Annex establishes general obligations to ensure that such services have access to and use of the public network on non-discriminatory and reasonable terms and conditions. Mexico claims that the Annex does not confer any right to supply telecommunications transport networks and services (i.e. basic telecommunications services) other than as provided in a Member's Schedule. It further submits that market access rights for the supply of basic telecommunication services were the subject of the later negotiations that led to the Fourth Protocol.572

4.308 The United States maintains that the Annex requires each WTO Member to ensure that foreign service suppliers have reasonable and non‑discriminatory access to and use of public telecommunications networks and services to supply a scheduled service. According to Section 5 of the Annex:

"(a) Each Member shall ensure that any service supplier of any other Member is accorded access to and use of public telecommunications transport networks and service on reasonable and non‑discriminatory terms and conditions for the supply of a service included in its Schedule. This obligation shall be applied, inter alia, through paragraphs (b) through (f) [footnote omitted].

(b) Each Member shall ensure that service suppliers of any other Member have access to and use of any public telecommunications transport network or service offered within or across the border of that Member, including private leased circuits."573

4.309 The United States submits that for each service inscribed in its Schedule, including basic telecom services, each WTO Member must ensure that foreign service suppliers may access or use public telecommunications networks and services � whether through interconnection or any other form of access and use � to transport their service.574 According to the United States the scope of this obligation is wide and extends to any public telecom network and service offered within or across the border of that Member. The definition of such networks and services is broad enough to encompass all types of public networks and services that a telecom provider may offer.575

4.310 Mexico submits that the focus of the Annex on Telecommunications services is as a transport means for other economic activities, and not the supply of basic telecommunications services.576 The term "access to and use of" is not defined in the Annex, but paragraphs (b) and (c) of Section 3 of the Annex define the terms "public telecommunications transport service"577 and public telecommunications transport networks".578 In Mexico's view, the Annex applies to access to and use of a Member's available basic telecommunications services. The services for which "access to and use of" is provided are something other than basic telecommunication services.579 Mexico contends that the United States' claims under the Annex must be assessed within the context of these definitions. Mexico points out that the United States is arguing that the Annex grants to its suppliers of basic telecommunications services the right to "supply" basic telecommunications services cross-border into Mexico by interconnecting with the public network or by interconnecting with private leased or owned circuits in Mexico. It further points out that the United States is also arguing that the Annex grants foreign companies the right to own 100 per cent of operators established in Mexico who will be entitled to supply such services cross-border into the United States.580

4.311 The United States claims that Mexican law prevents foreign suppliers from owning public telecom networks and services in Mexico, leaving them no choice but to rely on Mexican operators to provide the access to and use of the public networks and services they need to deliver scheduled basic telecom services from abroad into Mexico. Because of Telmex's monopoly over the negotiation of settlement rates and the requirement that all other Mexican carriers must charge the rate negotiated by Telmex, all Mexican operators are required to charge rates that exceed cost.581 According to the United States, the entire purpose of Section 5 of the Annex is to require WTO Members to prevent this very form of behavior. The United States claims that Members drafted the Annex to ensure that their suppliers of public networks and services � whether they are monopolies, major suppliers, or competitive suppliers � do not hold access to, and use of, their networks and services hostage to monopoly rates, or any other form of unfair or anti‑competitive conduct that would undermine the supply of scheduled services.582

4.312 In Mexico's view, the purpose of the Annex is not to allow facilities-based and non-facilities-based basic telecommunications suppliers to supply their services cross-border, but to provide supplementary or additional obligations to allow "access to" and "use of" Mexico's existing public telecommunications transport network and services.583 It submits that the terms "access to" and "use of" have different meanings from the term "supply", which is frequently used in the text of the GATS. The term "supply" is defined as meaning "provide or furnish a thing needed". Mexico claims that the Annex applies only to measures which affect "access to or use of public telecommunications transport networks or services, and it does not apply to measures that affect "supply" of telecommunications transport services cross-border.584 According to Mexico, the United States is confusing "market access" with "access to and use of" existing public telecommunications transport networks operated by domestic concessionaires. Mexico contends that "market access" is dealt with in the market-access commitments made under Article XVI of the GATS inscribed in Mexico's Schedule, whereas "access to and use of" public telecommunications networks is dealt with in the Annex.585

4.313 In Mexico's view, the Annex was not drafted to provide "market access" to foreign suppliers of basic telecommunications services.586 According to Mexico, paragraph (c) of Section 2 of the Annex provides important exemptions from the application of the Annex:

"Nothing in this Annex shall be construed:

(i) to require a Member to authorize a service supplier of any other Member to establish, construct, acquire, lease, operate, or supply telecommunications transport networks or services, other than as provided in its Schedule; or

(ii) to require a Member (or to require a Member to oblige service suppliers under its jurisdiction) to establish, construct, acquire, lease, operate or supply telecommunications transport networks or services not offered to the public generally."587

4.314 According to Mexico, the services at issue in this dispute are "telecommunications transport � services", governed by Mexico's Schedule. In Mexico's view, pursuant to Section 2(c)(i), nothing in the Annex can be construed to require Mexico to authorize service suppliers from the United States to supply these services beyond the terms and conditions inscribed in its schedule.588 The United States submits that Section 1 of the Annex states that telecommunications has a "dual role as a distinct sector of economic activity and as the underlying transport means for other economic activities." It further submits that Section 2(a) states that the Annex applies to "all measures" affecting access to and use of public telecommunications transport networks and services, which would include measures regulating telecommunications "as a distinct sector of economic activity . . ." The United States also recalls Section 5(a), which imposes obligations "for the supply of a service included in [a Member's] Schedule," without imposing any limits on the type of service that would be relevant, including basic telecommunications services scheduled by Mexico.589

4.315 Mexico maintains that the fact that Section 1 (entitled "Objectives") of the Annex on Telecommunications refers to a "dual" role of the telecommunications services sector does not mean that the Annex covers both aspects of this "dual" role. In Mexico's view, Section 1 simply confirms that the Annex is based on the recognition that, beyond constituting a service sector of their own, telecommunications services and networks are essential tools for other economic activities, such as banking, insurance, etc. According to Mexico the fact that these other activities rely heavily on telecommunications services as an underlying transport means that is the raison d'�tre of the Annex, supporting Mexico's view that the Annex is aimed at addressing the second aspect of the dual role. The first aspect � the supply of basic telecommunications services � was dealt with under the basic telecommunications negotiations that led to the Fourth Protocol to the GATS in 1997.590 Although Section 1 refers to a "dual" role of the telecommunications services sector, it also stipulates that the Annex was agreed to "with the objective of elaborating upon the provisions of the Agreement with respect to measures affecting access to and use of public telecommunications transport networks and services".591 The reference in Section 1 of the Annex to "measures affecting access to and use of" PTTNS must be contrasted with the scope of the provisions of the GATS Annex on Financial Services. Section 1(a) of that Annex states "[t]his Annex applies to measures affecting the supply of financial services. Reference to the supply of a financial service shall mean the supply of a service as defined in paragraph 2 of Article I of the Agreement". Thus, where the negotiators of the GATS intended that an annex apply to the "supply" of a service within the broader meaning of the GATS, they did so explicitly.592

4.316 According to Mexico the Annex distinguishes between access to and use of public telecommunications transport networks and services, which is relevant to telecommunications services as an underlying transport means for other economic activities, and the supply of such services, which is relevant to trade in telecommunications services as a distinct sector of economic activity.593 In Mexico's view, Section 2 of the Annex makes clear that the Annex is devoted solely to the guarantees of access and use. It explains that Paragraph (a) of Section 2 stipulates that the Annex "shall apply to all measures of a Member that affect access to and use of public telecommunications transport networks and services". In Mexico's view, the Annex is limited in scope and deals only with the right to access and use public telecommunications transport networks and services and not the right to provide and supply them.594 Mexico contends that the services at issue in this dispute are the transport of customer-supplied information or data between two or more points, being themselves "public telecommunications transport networks and services", which cannot be supplied through access to and use of another Member's PTTNS.595 It further submits that, by definition, Mexico's suppliers of "public telecommunications transport networks and services" cannot transport public telecommunications transport services supplied by other suppliers. It explains that, in the circumstances of this dispute, when suppliers from the United States hand off traffic to a Mexican supplier at the border, they rely on the PTTNS provided by that supplier and do not supply their services into Mexico. Mexico contends that basic telecommunications services are the underlying transport means for other economic activities and Mexico fails to see how they could be viewed as a transport means for the same economic activity, which is the implication of the United States' position in this dispute.596

4.317 Answering a question by the Panel597, Mexico submits that Section 5 of the Annex refers to access to and use of a Member's PTTNS "for the supply of a service included in its schedule", that applies only until the services scheduled by a Member can be supplied by access to and use of another Member's PTTNS.598 According to Mexico, the services that are the subject of this dispute are telecommunications transport and transmission services, which cannot ipso facto be supplied through access to and use of another Member's PTTNS since the latter are, in themselves, "public telecommunications transport networks and services".599 Mexico contends that the United States interpretation would lead to the conclusion that the Mexican postal authority would be transporting United States postal services by delivering mail sent from the United States and handed over at the border, that a pipeline within Mexican territory would be transporting United States pipeline services when it transports oil received from a United States pipeline that stops at the border, and that a Mexican transport company would be performing United States transport services when it delivers the freight that was transferred to it at the border. In Mexico's view, Mexican service suppliers � including public telecommunications transport suppliers � only supply their own transport service.600

4.318 The United States contends that Mexico's assertion that the services at issue are "transport and transmission" services, is erroneous, as it ignores the text of the CPC codes Mexico has inscribed in its Schedule. In the view of the United States, Mexico's Schedule does not limit its cross-border commitment to only a portion of the service defined in the CPC codes, but the entirety of a telephone call's path, from its point of origin to its point of termination.601 The United States further disagrees with the analogy that Mexico draws with regard to the transport of oil or of goods sent via mail. In case of the transport of goods, the goods are separate products, while a basic telecommunications service � a telephone call or a "communication" is an inseparable part of the service itself. Section 1 of the Annex draws an explicit distinction between telecommunications services as a distinct sector of economic activity and as the underlying transport means for other economic activities.602

2. Application of Sections 5(a) and 5(b) of the Annex

4.319 The United States submits that, its claims are related to five distinct situations for which, in the United States' view, Mexico has made specific commitments, and for which Mexico must comply with its Annex obligations. According to the United States, under the first two situations, in accordance with Section 5(a) of the Annex, Mexico must ensure that foreign facilities-based and non-facilities based suppliers of cross border telecommunications services are accorded access to and use of public telecommunications transport networks and services (PTTNS) on reasonable and non-discriminatory terms and conditions.603 Under the third and fourth situations, the United States claims that, according to Section 5(b) of the Annex, Mexico must ensure that these suppliers have access to and use of private leased circuits.604 The United States further points out that locally established non-facilities based operators (commercial agencies) must likewise be afforded access to and use of private leased circuits to supply international telephone services.605

(a) Claims under Section 5(a) of the Annex

4.320 According to the United States, pursuant to the Annex, services suppliers from the United States are entitled to access and use of public telecommunications networks and services. The United States claims that interconnection is the means by which service suppliers from the United States access and use Mexico's public telecommunications networks and services. The United States asserts that its service suppliers must interconnect with the Mexican network in order to ensure they can transport their scheduled service to its final destination in Mexico. The United States further points out that without such access, a service supplier from the United States could never supply a scheduled facilities‑based or non‑facilities‑based basic telecom service.606

4.321 United States submits that Section 5 of the Annex requires Mexico to ensure that for the supply of a service included in its Schedule, any service supplier of any other Member is accorded access to and use of public telecom transport networks and services on reasonable terms and conditions.607

4.322 The United States claims that Mexico undertook market access and national treatment commitments for public basic telecom services supplied by facilities‑based operators and non‑facilities‑based operators ("commercial agencies"). In the United States' view, Mexico undertook these obligations on a cross‑border basis, with few limitations, applying to the supply of cross-border public basic telecom services supplied by facilities‑based operators and commercial agencies.608

4.323 The United States also claims that Mexico's Annex obligations apply to any service supplier from the United States (whether facilities‑based or non‑facilities‑based) wishing to supply the scheduled basic telecom services.609

4.324 The United States submits that the Annex imposes a broad obligation upon Members to ensure - by whatever measures necessary610 � that service suppliers have broad access to and use of public telecom networks and services to transport their services.611 In the United States' view, interconnection, as defined by Section 2.1 of the Reference Paper612, is the principal method for suppliers from the United States to obtain access and use of Mexican public telecommunications networks and services for the cross-border supply of scheduled basic telecom services.613

4.325 The United States claims that Mexican law prohibits foreign suppliers from owning public telecom networks and services in Mexico614, preventing such suppliers of scheduled basic telecom services to originate and terminate services over their own networks. The United States submits that its suppliers have no choice but to rely on Mexican suppliers of public telecom networks and services � such as Telmex and others � to transport their service to its final destination.615 According to the United States, this interconnection of its suppliers can take two principal forms: (1) a facilities-based supplier of the scheduled basic telecom services who links its network with that of a Mexican supplier616; or (2) a supplier who does not own facilities and interconnects by leasing circuits from other operators with Mexican public networks and services.617

4.326 Mexico contends that in its Schedule, for the subsector of "Telecommunications services supplied by a facilities based public telecommunications network through any existing technological medium �", it specifically inscribed in the column "Limitations on Market Access" the following limitations on the modes of supply of (1) cross border-supply and (3) commercial presence:

"(1) None, except the following:

International traffic must be routed through the facilities of an enterprise that has a concession granted by the Ministry of Communications and Transport (SCT).

(3) A concession from the SCT is required. Only enterprises established in conformity with Mexican law may obtain such a concession.

Footnote 1 � Concession: The granting of title to install, operate or use a facilities-based public telecommunications network."618

4.327 The United States submits that unlike the term "non-discriminatory", the Annex does not define "reasonable". In the United States view, to determine the scope of "reasonable" terms and conditions, a treaty interpreter should look to the ordinary meaning of "reasonable" in its context and in light of the object and purpose of the Annex and the GATS.619 According to the United States, the terms and conditions that Mexico has imposed are unreasonable under the object and purpose of the Annex and the GATS.620

4.328 Mexico contends that the term "reasonable" set out in Section 5(a) of the Annex does not have the same meaning as the term "reasonable" set out in Section 2.2 of the Reference Paper.621 In Mexico's view, although the ordinary meaning is applicable to the term "reasonable" in both provisions, Section 5(a) of the Annex and Section 2.2(b) of Mexico's Reference Paper provide different contexts for interpreting its meaning.622

4.329 Mexico submits that in US � Definitive Safeguard Measures on Imports of Wheat Gluten from the European Communities, the Appellate Body stated that "[i]n view of the identity of the language in the two provisions, and in the absence of any contrary indication in the context, we believe that it is appropriate to ascribe the same meaning to this phrase in both Articles 2.1 and 2.2".623 In Mexico's view, where identical language is used in two provisions, it is only appropriate to ascribe the same meaning to the language where there is an "absence of any contrary indication in the context". Mexico contends that the different context of the term "reasonable" in the two provisions necessitates that a different meaning be ascribed to the term. According to Mexico, Section 5(a) of the Annex applies to "access to and use of public telecommunications transport networks" on terms and conditions that are inter alia, "reasonable", while Section 2.2(b) applies to interconnection with a major supplier on, inter alia, cost-oriented rates that are "reasonable". In its view, the two provisions address different subject matters. Mexico claims that these different contexts are important, particularly when interpreting the meaning of a word like "reasonable". Mexico further submits that reasonableness can be judged only within the context of all relevant facts and circumstances because it is those facts and circumstances that provide a basis for reason and expectation.624 Mexico further points out that, in determining whether a service supplier of another Member is accorded "access to and use of public telecommunications transport networks" on terms and conditions that are inter alia, "reasonable", the Panel must examine all relevant facts and circumstances related to access to and use of PTTN.625

(b) Claims under Section 5(b) of the Annex

4.330 The United States submits that Section 5(a) of the Annex requires Mexico to ensure that service suppliers of other Members can access and use public telecom networks and services on reasonable terms and conditions to provide a scheduled service.626 The United States further submits that, to this end, Section 5(b) of the Annex requires Mexico to ensure that foreign suppliers can access and use private leased circuits offered within and across Mexico's border and interconnect those circuits with public networks and services.627 Consequently, both facilities and non-facilities based suppliers of cross-border telecom services must have access to and use of private leased circuits. Further, established non-facilities based operators (commercial agencies) must likewise be afforded access to and use of private leased circuits under reasonable terms and conditions, to supply scheduled basic telecom services. In the United States' view, Mexico's measures preclude foreign suppliers from offering scheduled basic telecom services over private leased circuits; and are therefore violating the basic obligation to provide access to and use of private leased circuits for the provision of a scheduled service by Mexico.628

4.331 Mexico contends that under Mexican law, only companies established in Mexico and qualifying for a "concession" may "install, operate or use a facilities-based public telecommunications network". It contends that under Mexican law, suppliers of facilities-based telecommunications services from the United States are not permitted to provide facilities-based telecommunications services in Mexico. Mexico further submits that it made clear, by specifically inscribing limitations in its Schedule, that suppliers of facilities-based telecommunications services from the United States would not be permitted to supply basic telecommunications services cross-border.629

4.332 The United States submits that Section 5(b) contemplates both principal forms of interconnection, as follows:

"Each Member shall ensure that service suppliers of any other Member have access to and use of any public telecommunications transport network and service offered within or across the border of that Member, including private leased circuits, and to this end shall ensure, subject to paragraphs (e) and (f), that such suppliers are permitted . . . (ii) to interconnect private leased or owned circuits with public telecommunications transport networks or with circuits leased or owned by another service supplier."630

4.333 Mexico claims that there is no basis for the allegation from the United States that Mexico committed itself to cross-border access for facilities-based suppliers of basic telecommunications.631 According to Mexico, the language of Section 5(b) explicitly demonstrates that WTO Members intended and expected that "access to and use of any public telecommunications transport network or service" was something that could be "offered" or not "offered", within or across the border of a particular Member. Mexico claims that it did not "offer" or commit itself to "access to or use of" a public telecommunications transport network or service either within Mexico or across its border. In Mexico's view, two provisions of a treaty - Sections 2(c)(i) and 5(b) - should not be interpreted in a manner which renders one of them ineffective or inutile.632

4.334 According to the United States, Section 5(b) specifically guarantees that foreign service suppliers may obtain access to and use of Mexican public telecom networks and services through interconnection of private leased or owned circuits.633 The United States maintain that, in both cases, its service suppliers must rely on interconnection with a Mexican supplier of public telecom networks and services � such as Telmex � in order to access and use Mexican public telecom networks and services for the supply of a scheduled basic telecom service between the United States and Mexico. In the United States' view, Mexico must therefore ensure � under Section 5 of the Annex � that suppliers of scheduled basic telecom services from the United States may interconnect with Mexican suppliers on reasonable terms and conditions.634

4.335 In Mexico's view, Section 2(c)(i) of the Annex exempts Mexico from allowing non-facilities-based suppliers of basic telecommunications services to supply their services cross-border over capacity that they lease from operators in Mexico. Mexico claims that to interpret the Annex otherwise would not only be inconsistent with the provisions of Section 2(c)(i) of the Annex, but would also undermine and render ineffective the express language of the limitations on Market Access inscribed in Mexico's GATS Schedule.635

4.336 According to the United States, private leased circuits are essentially lines that a user leases from a public telecom operator over which it transports (or supplies) its service. As an example, the United States explains that a bank might lease a line from a public telecom operator over which it sends financial information from its branch in Mexico City to its home office in New York, or a telecommunications company may lease a line from a public telecom operator over which its sends a phone call from its customer in Los Angeles to the end-user in Montreal. In the United States' view, in both cases the service supplier (the bank or the phone company) needs access to a line (a public telecom network or service) to provide a scheduled service (a financial service or a basic telecom service).636 It claims that Mexico has not ensured that suppliers from the United States have access to and use of any public telecommunications network and service for the supply of the basic telecom services inscribed in Mexico's Schedule637, failing to honour its commitments under the Annex.638

4.337 Mexico submits that, even if the Annex were to apply to this dispute, the terms and conditions that Mexico applies on access to and use of PTTNS would have to be considered reasonable. According to Mexico, the Annex allows WTO Members great latitude to regulate access to and use of PTTNS. In Mexico's view the word "reasonable" in Section 5(b) would have to be interpreted broadly to include all relevant facts and circumstances related to interconnection, including the economic feasibility of the terms of access to the Mexican carrier and Mexico.639

4.338 According to the United States, Section 5(b) of the Annex requires Mexico to ensure that service suppliers of any other Member. "(ii) interconnect private leased or owned circuits with public telecommunications transport networks and services or with circuits leased or owned by another supplier". In the United States view, because the obligation in Section 5(a) of the Annex apply to paragraph (b), Mexico must ensure that foreign suppliers have access to and use of such private leased circuits on reasonable terms and conditions for the supply of scheduled services. The United States further points out that in this case, the analysis need not to extend to whether the "terms and conditions" are reasonable and non‑discriminatory, because Mexico has failed to ensure any access to and use of private leased circuits for the supply of scheduled services640, acting inconsistently with its obligations under Section 5(a) and (b) of the Annex.641

4.339 The United States claims that Mexico has failed to comply with Section 5 of the Annex with respect to the market access and national treatment commitments it undertook for the: (1) cross‑border (mode 1) supply of facilities‑based basic telecom services; and (2) the cross‑border (mode 1) and domestic (mode 3) supply of non‑facilities‑based basic telecom services. The United States submits that, to avoid any confusion, the claims it makes related to private leased circuits address the delivery of scheduled public basic telecom service using private leased circuits.642

4.340 The United States contends that Mexico scheduled market access and national commitments to allow non‑facilities‑based suppliers ("commercial agencies") to provide basic circuit‑switched telecom services to third parties over a private (i.e., dedicated) circuit that it leases from a concessionaire.643 The United States recalls that according to Mexico's Schedule, commercial agencies do not supply basic telecom services over their owned facilities but over capacity they lease from a licensed facilities-based telecom operator.644 The United States points out that the supply of telecommunications over leased capacity is typically known as "resale", but Mexico's Schedule uses the phrase "commercial agencies".645 The United States recalls that "leased capacity" is essential to the supply of this scheduled service, because without access to such capacity, a commercial agency cannot, according to Mexico's definition, supply its service. The United States submits that private leased circuits � not defined in the Annex � are generally understood to mean telephone lines leased from a phone company that are specifically dedicated to a customer's use.646

4.341 The United States submits that Mexico undertook these commitments for the cross‑border supply of services (mode 1) over leased capacity from the territory of one Member (e.g., the United States) into the territory of any other Member (i.e., Mexico). According to the United States, Mexico limited this mode 1 commitment to ensure that foreign commercial agencies route international traffic through the facilities of a "concessionaire". The United States claims that Mexico committed to allow a foreign, non‑facilities‑based supplier to offer telecom services from the territory of the United States into the territory of Mexico over capacity leased from a public network concessionaire (i.e., private leased circuits). The United States points out that the cross‑border supply of a basic telecom service over leased capacity is typically known as International Simple Resale (ISR).647

4.342 The United States recalls that Mexico also undertook commitments for locally-established (mode 3) commercial agencies, with certain limitations. The United States points out that a foreign service supplier should be able to own 100 per cent of a locally established commercial agency, because Mexico did not schedule a foreign ownership limitation for such services. The United States argues that, because Mexico did not indicate otherwise, this mode 3 commitment allows a locally established commercial agency to provide international basic telecom services over leased capacity.648

4.343 The United States contends that Mexico undertook mode 1 and mode 3 commitments for services, which require access to and use of private leased circuits for their supply. The United States claims that its suppliers cannot supply basic telecom services over leased capacity on a cross-border basis if they cannot lease private leased circuits from a Mexican supplier. The United States further points out that its suppliers can not establish a commercial presence to supply international basic telecom services over leased capacity if they cannot lease private leased circuits from a Mexican supplier. The United States recalls that Mexico does not permit its basic telecom service suppliers to lease such circuits for these services and therefore precludes the supply of mode 1 and mode 3 commercial agency services.649

4.344 Mexico submits that with respect to access through commercial presence for non-facilities based suppliers, the United States argues that Mexico committed to the establishment of commercial agencies and to the provisions of services by such agencies through private leased circuits, i.e. ISR.650 Mexico claims that its mode 3 (commercial presence) commitment for commercial agencies is subject to the following limitations:

"A permit issued by the SCT is required. Only enterprises set up in accordance with Mexican law may obtain such permit.

Foreign governments may not participate in an enterprise set up in accordance with Mexican law nor obtain any authorization to provide telecommunication services.

Except where specifically approved by the SCT, public telecommunications network concessionaires may not participate, directly or indirectly, in the capital of a commercial agency.

The establishment and operation of commercial agencies is invariably subject to the relevant regulations. The SCT will not issue permits for the establishment of a commercial agency until the corresponding regulations are issued."651

4.345 Mexico submits that the permit requirement is central to the limitation. According to Mexico, because at the time the limitation was inscribed, permits were not issued by the SCT, then it is equivalent to a zero quota, falling the requirement within the category of "limitations on the number of service suppliers" in paragraph (a) of GATS Article XVI:2.652

4.346 Answering a Panel's question653, the United States contends that Mexico's refusal to adopt regulations necessary to issue commercial agency permits violates Mexico's obligation under Section 5(b) of the Annex on Telecommunications to ensure that service suppliers have access to and use of private leased circuits.654 The United States further submits that Telmex, through its subsidiary in the United States, assured the FCC that Mexico's WTO commitments requires Mexico "promptly" to adopt the relevant regulations and issue reseller permits.655

4.347 The United States submits that Mexico also undertook cross‑border market access and national treatment commitments for specific public basic telecom services supplied by a facilities‑based operator. According to the United States, Mexico limited this commitment to ensure that foreign service suppliers route international traffic through the facilities of a Mexican concessionaire. The United States contends that, for the supply of these public facilities‑based services from the territory of the United States into the territory of Mexico, Mexico promised to accord market access and national treatment to suppliers of these services provided that the service supplier, from the United States, routes international traffic through the facilities of a Mexican concessionaire.656

4.348 According to the United States, access to and use of private leased circuits is essential to the supply of the following services inscribed in Mexico's Schedule: (a) facilities‑based services (i.e., voice telephone, circuit‑switched data, facsimile services by a facilities‑based operator from the United States into Mexico) supplied on a cross‑border basis; (b) commercial agencies (i.e., basic telecom services by a non‑facilities‑based operator over leased capacity from the United States into Mexico) supplied on a cross‑border basis; and (c) locally established commercial agencies (i.e., basic telecom services by a non‑facilities‑based operator over leased capacity from Mexico into the United States). The United States claims that Mexico has failed to ensure that private leased circuits are available for the supply of these scheduled services.657

4.349 The United States submits that Mexico committed under Section 5(a) and (b) to ensure that foreign facilities-based suppliers, foreign commercial agencies and locally established commercial agencies have access to and use of private leased circuits to supply scheduled international basic telecom services over such circuits and can interconnect such circuits with public telecom networks and services. The United States contends that because Mexican suppliers offer private leased circuits to their customers, then Mexico must ensure that these circuits are available to all suppliers of scheduled basic telecom services. The United States claims that foreign suppliers do not have access to and use of private leased circuits to supply scheduled basic telecom services.658 The United States further submits that Mexican suppliers have refused to provide these circuits, Mexican law prevents foreign basic telecom service suppliers from using such circuits, and Mexican authorities continue to refuse to permit the supply of scheduled services over leased capacity. According to the United States, these restrictions prevent foreign service suppliers from accessing and using private leased circuits to supply scheduled basic telecom services.659

4.350 The United States submits that its suppliers based in the United States have no access to private leased circuits for the supply of scheduled basic telecom services and even if they did, Mexican ILD Rules prevent foreign suppliers from interconnecting private leased circuits with public telecom network services, violating the obligation to provide access to and use of private leased circuits.660 It claims that Telmex has refused to make private leased circuits available for the cross-border supply of scheduled voice telephone services661, and that Mexican authorities have done nothing to ensure that Telmex or any other supplier provides these leased circuits to suppliers from the United States for the cross-border supply of scheduled basic telecom services.662

4.351 The United States contends that Mexico not only has failed to ensure that its suppliers provide private leased circuits to foreign suppliers for the cross‑border supply of scheduled basic telecom services but has also maintained measures that preclude foreign suppliers from ever using these circuits to supply such services.663 The United States recalls that under Mexico's ILD Rule 3664, a foreign supplier cannot interconnect a private circuit leased in Mexico with foreign public networks and services for the provision of scheduled basic telecom services.665 The United States submits that according to this Rule, only "international port operators" may interconnect with the public telecommunications networks of foreign operators in order to supply basic telecom services, but Mexican ILD Rules require an international port operator to be a supplier with a concession to supply long-distance services and Mexican law prohibits non‑Mexican entities from holding such a concession, since Mexico inscribed this nationality restriction for concessionaires in its Schedule.666

4.352 The United States contends that the interconnection of a private circuit leased in Mexico with the public telecom network in the United States is essential to the cross-border provision of public basic telecom services over private leased circuits, which is a commitment included in Mexico's Schedule. Because a non facilities-based service supplier cannot be a long-distance concessionaire, it cannot interconnect a private circuit leased in Mexico with the public telecom network in the United States, as it is unable to supply the scheduled public telecom service.667

4.353 The United States submits that Mexico undertook cross‑border commitments for "commercial agencies", which Mexico defined as the supply by non‑facilities‑based providers of telecommunications services to third parties over capacity leased from a Mexican concessionaire. According to the United States, by Mexico's definition, the supply of this international "resale" service requires a Mexican concessionaire to provide a foreign service supplier access to and use of private leased circuits. The United States claims that without such circuits, foreign suppliers cannot provide cross‑border telecom services as commercial agencies.668 The United States recalls that Sections 5(a) and (b) of the Annex ensure that foreign commercial agencies have access to and use of these circuits and can interconnect these circuits with public telecom networks and services on reasonable terms and conditions to provide "resale" services on a cross‑border basis � services that cannot be supplied without such circuits. In the United States' view, Mexico has failed to comply with these commitments, prohibiting foreign service suppliers from offering this "resale" service that it scheduled. The United States further points out that even if Mexico permitted foreign suppliers to offer this "resale" service, ILD Rule 3 precludes the supply of this service by preventing all commercial agencies (domestic and foreign) from interconnecting private leased circuits with foreign telecom networks.669

4.354 The United States submits that the policy of the Mexican Government � since undertaking commitments for commercial agencies � has been to refuse to permit any foreign carrier from supplying international "resale" services (i.e., international telecom services supplied over private leased circuits). Eight months after finalizing its "commercial agencies" commitments, the then‑Secretary of Mexico's Secretariat of Communications and Transportation (SCT) wrote a letter to the then‑Chairman of the FCC stating that the policy of his Government was to forbid the resale of "long‑distance public network capacity in Mexico".670 The United States claims that, in other words, although Mexico had committed to its WTO partners that it would permit commercial agencies to provide all forms of telecommunications services to third parties over resold capacity, Secretary Ruiz Sacrist�n affirmed that Government of Mexico had no intention of allowing telecom operators to do so.671 The United States further submits that Secretary Ruiz Sacrist�n reaffirmed this position in a 8 May 1998 letter to then‑USTR Charlene Barshefsky. According to the United States, Ambassador Barshefsky wrote to both Secretary Ruiz Sacrist�n and Secretary Herminio Blanco Mendoza (then‑Secretary of Commerce and Industrial Development) on 4 April 1998 to express her deep concern over Mexico's implementation of its GATS basic telecom commitments, including "Mexico's failure to permit unrestricted domestic and international resale of telecommunications services (including international simple resale)".672 The United States recalls that Secretary Ruiz Sacrist�n responded that Mexico's WTO commitments did not include these services.673

4.355 The United States contends that, by expressing his Government's refusal to permit the domestic and international resale of telecommunication services, Secretary Ruiz Sacrist�n acknowledged Mexico's failure to honour its scheduled commitment to allow "commercial agencies" to supply cross‑border telecommunications services to third parties over leased capacity (i.e., private leased circuits).674

4.356 According to the United States, Mexico undertook a mode 3 commitment for commercial agencies promising to permit foreign suppliers to acquire a 100 per cent interest in a local non-facilities-based supplier and offer international telecommunications services to third parties over capacity leased from a Mexican concessionaire. The United States points out that the supply of this international "resale" service requires a Mexican concessionaire to provide a foreign service supplier access to and use of private leased circuits.675 The United States further submits that Sections 5(b) of the Annex obliges Mexico to ensure that foreign service suppliers: (1) have access to and use of the private leased circuits they need to supply this scheduled resale service; and (2) can interconnect such circuits with public telecom networks and services. The United States claims that Mexico has failed to comply with these obligations by not permitting non‑facilities‑based service suppliers (commercial agencies) to establish locally and supply international telecom services from Mexico over private leased circuits. The United States further points out that ILD Rule 3 prevents all commercial agencies from interconnecting private leased circuits with foreign telecom networks, preventing Mexico from complying with its commitments under the Annex.676

4.357 The United States submits that to its knowledge, Mexico does not permit foreign non‑facilities‑based suppliers to establish locally and supply third parties international telecommunications services over private leased circuits.677 The United States recognizes that Mexico conditioned the mode 3 supply of "commercial agencies" on the issuance of the relevance regulations, but claims that over five years have elapsed since Mexico finalized this commitment in February 1997 (and four years have elapsed since this commitment entered into force in February 1998), and Mexico still has not issued � and has indicated no intention to issue � the relevant regulations. According to the United States, the refusal to issue such regulations raises questions about whether Mexico ever intends to implement this scheduled mode 3 commitment for commercial agencies.678

4.358 Mexico replies that there is nothing in the wording of the limitations that indicates that Mexico has made a commitment to issue the corresponding regulation within a certain time-frame. According to Mexico, the issuance of the regulation is at the discretion of the Mexican authorities taking into account the transition occurring in the Mexican telecommunications market. Mexico claims that the fact that the regulation has not yet been issued does not nullify the limitation.679 Furthermore, Mexico has issued regulations for the establishment and operation of commercial agencies for pay-telephone public services. Based on those regulations, Mexico has granted 59 permits for public pay phone commercial agencies. 35 of those agencies have begun operations and five of them have foreign capital.680

4.359 The United States submits that it is not inconsistent with the obligation under Section 5(b) of the Annex to require that cross-border service suppliers route traffic through the facilities of a Mexican concessionaire. According to the United States, the routing requirement is one way in which a member may satisfy the obligation in Section 5(b). In its view, the routing requirement included in Mexico's Schedule, interpreted according to the rules of interpretation in the Vienna Convention, permit service suppliers from the United States to provide basic telecommunications services into Mexico over capacity leased from a Mexican concessionaire.681

4.360 In response to question No. 27 of the Panel on 19 December 2002, Mexico submits that Section 5(b) relates to "access to and use of" private leased circuits and the interconnection of those circuits with the PTTNS or with other leased circuits. Mexico notes that, in the context of the claims being raised by the United States, this provision does not entitle service suppliers of any other Member to supply public telecommunications services over private leased circuits. In Mexico's view, Section 5(b) does not entitle service suppliers of the United States to offer ISR into Mexico. According to Mexico, this interpretation is confirmed by Section 2(c)(i) which: (i) refers to Schedule limitations; and (ii) which refers to available services and networks. Mexico submits that its Schedule, which includes the routing restriction, denies any market access for service suppliers from the United States to provide ISR into Mexico.682 In the same line, Mexico submits that ISR services are prohibited under Mexican law as manifested in its Schedule. Therefore, ISR was "not offered to the public generally" within the meaning of Section 2(c)(i) of the Annex.683
