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. 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 escape clauses under which countries could negotiate exemptions if their domestic producers were particularly harmed by tariff reductions. In accordance with Article XXXIV, Schedules A to I are an integral part of the agreement. Tariff concessions attached to the general agreement (not reproduced here) are also part of the agreement, in accordance with Article II:7. The General Agreement on Tariffs and Trade (GATT), signed on 30 October 1947 by 23 countries, was a legal agreement to minimize barriers to international trade by eliminating or reducing quotas, tariffs and subsidies, while maintaining important rules.
The GATT is expected to stimulate economic recovery after the Second World War through the reconstruction and liberalization of world trade. The SPS agreement has changed the way trade decisions are made with respect to agricultural products. Its main intention is to facilitate trade and avoid the use of sanitary and plant health measures as unjustified barriers to trade. The agreement stipulates that all measures must be scientifically sound and should not be unnecessarily restrictive, while recognizing the right of countries to the protection of human, animal or plant life or health. 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.   In December 1993, after seven years of negotiations, GATT reached an agreement between 117 countries, including the United States. This cycle took place in Uruguay and was therefore called the Uruguay Round. The final act on the outcome of the multilateral trade negotiations of the Uruguay Round was the agreement reached during this round, signed in April 1994. The World Trade Organization (WTO) was created as part of this agreement. The WTO is implementing the agreement and has also launched the current round in Doha.
