The working hypothesis for collective bargaining was a linear reduction of 50% in tariffs, with the smallest number of exceptions. A long-term argument has developed about the trade effects of a uniform linear reduction on the dispersed rates (low tariffs and high rates quite far away) of the United States compared to the much more concentrated rates of the EEC, which also tended to be under the ownership of U.S. tariffs. MFN Treatment: Article II of the GATS authorizes members to treat the service providers of all other members without delay and unconditionally, “a treatment that is no less favourable than that given to comparable service providers in another country.” In principle, this is a prohibition of preferential regimes between groups of members in certain sectors or reciprocity rules that limit access to the dense to trading partners who give similar treatment. The details of the GATT were optimized in the decades following its creation. The main objective of the continuation of the negotiations was the continuation of the reduction of tariffs. In the mid-1960s, the Kennedy Round added an anti-dumping agreement. The Tokyo Round of the 1970s improved other aspects of trade. The Uruguay round lasted from 1986 to 1994 and created the World Trade Organization. In 1993, the GATT was updated (“GATT 1994”) and includes new commitments to its signatories. One of the most important changes was the creation of the World Trade Organization (WTO).
The current 76 members of THE GATT and the European Communities became founding members of the WTO on 1 January 1995. The remaining 51 GATT members re-joined the WTO over the next two years (the last being Congo in 1997). Since the creation of the WTO, 33 new GATT members have joined and 22 are currently negotiating membership. In total, the WTO has 164 member states, with Liberia and Afghanistan being the most recent members from 2018. Exceptions may be granted in the form of Article II exceptions. Members could apply for such exemptions before the agreement came into force. New derogations may only be granted to new members at the time of accession or, in the case of current members, by a derogation under Article IX:3 of the WTO agreement. All exceptions are subject to review; they should not, in principle, last more than 10 years. In addition, the GATS allows groups of members to enter into economic integration agreements or to mutually recognize regulatory standards, certificates and others when certain conditions are met.
Since then, there has been a dispute over whether this symbolic gesture was a victory for it or whether it was excluded in the future from meaningful participation in the multilateral trading system. On the other hand, there is no doubt that the three-year extension of the international cotton textile trade agreement, which has become a multi-net agreement, has had the effect of hampering developing countries` export opportunities in the longer term. In accordance with Article XXI, specific obligations may be amended subject to certain procedures. Countries likely to be affected by such changes may invite the changing member to negotiate compensatory adjustments; these must be conceded on the basis of the MFN. In 1947, the average tariff for large GATT participants was about 22%.  As a result of the first rounds of negotiations, tariffs at the heart of the GATT of the United States, the United Kingdom, Canada and Australia have been reduced relative to other contracting and non-GATT countries.  During the Kennedy Round (1962-67), the average level of tariffs for GATT participants was about 15%.  After the Uruguay Round, tariffs were less than 5%.  The Uruguay Round Agricultural Agreement remains the most important agreement on agricultural trade liberalization in the history of trade negotiations.
