In 1947, the average tariff for large GATT participants was about 22%. [4] 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. [4] During the Kennedy Round (1962-67), the average level of tariffs for GATT participants was about 15%. [4] After the Uruguay Round, tariffs were less than 5%. [4] This series of meetings and reduced rates would continue, allowing new GATT provisions to be incorporated into the process. The average tariff rate rose from about 22% when the GATT was first signed in Geneva in 1947, to about 5% until the end of the 1993 Uruguay Cycle, which also negotiated the creation of the WTO. Tariffs (preferably quotas, but still an obstacle to trade) have in turn been constantly reduced in successive rounds of negotiations. However, this part of the result was not authorized by Congress and the U.S. selling price was not abolished until Congress passed the results of the Tokyo Round.

The results in agriculture as a whole have been poor. The most notable achievement was the agreement on a Memorandum of Understanding on the basic elements for the arrangement of global subsidies, which was eventually incorporated into a new international agreement on cereals. The assertion that Article 24 could be used in this way has been criticized as unrealistic by Mark Carney, Liam Fox and others, as point 5c of the contract requires an agreement between the parties so that Article 5b can be useful, since there would be no agreement in the case of a non-agreement scenario. In addition, critics of the GATT 24 approach point out that services would not fall under such regulation. [28] [29] The Doha Development Round began in 2001. The Doha Round began in 2001 with a ministerial meeting in Doha, Qatar. The aim was to focus on the needs of developing countries. The main factors examined are trade facilitation, services, rules of origin and dispute resolution. Special and differentiated treatment of developing countries was also discussed as a principal. The following ministerial meetings were held in Cancer, Mexico, in 2003 and Hong Kong (2005). These negotiations took place in Paris, France (2005), Potsdam, Germany (2007) and Geneva, Switzerland (2004, 2006, 2008). Progress in the negotiations stalled after negotiations broke down in July 2008.

[17] [18] The existence of specific commitments entails other obligations, including notification of new measures that have a significant impact on trade and the prevention of restrictions on international payments and transfers. In 1993, the GATT was updated (“GATT 1994”) to take on new obligations 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. One of GATT`s most important achievements has been indiscriminate trade.

Any GATT signatory should be treated like any other, known to be the nation`s most privileged principle and entered into the WTO. The practical result was that, once a country had negotiated a tariff reduction with some other countries (usually its major trading partners), this reduction would automatically apply to all GATT signatories. There were leakage clauses allowing countries to negotiate exemptions if their domestic producers were particularly harmed by tariff reductions. The fifth cycle took place again in Geneva and lasted from 1960 to 1962.
