The North American Free Trade Agreement (NAFTA) is an agreement signed by the governments of Canada, Mexico and the United States that creates a trilateral trade bloc in North America. The agreement came into force on January 1, 1994. It replaced the free trade agreement between the United States and Canada. The GATT came into force on January 1. 1, 1948. Since that beginning, it has been refined, which eventually led to the creation, on 1 January 1995, of the World Trade Organization (WTO), which absorbed and expanded it. To date, 125 nations signed their agreements, which covered about 90% of world trade. Prior to the establishment of the World Trade Organization (WTO) on 1 July 1995, imports from third countries were dependent on imports. These taxes are now converted into a fixed tariff, payable in euros per tonne or as a percentage of the entry price.
Under the agreement, rates were reduced by an average of 36% compared to the 1986-1988 reference period. In addition, the GATT/WTO agreement provides minimum quotas for access to tariffs at reduced rates of 5% of consumption over the reference period. In addition, the European Union is obliged to grant access to butter originating in New Zealand at a very low rate. This amount is the average amount of Annual exports from New Zealand to the United Kingdom under bilateral agreements during the GTT and WTO base period. Following the commitments of THE GATT and the WTO, the European Union has concluded a series of bilateral agreements aimed at facilitating market access on a reciprocal basis. For example, there are special quotas for the United States, Canada, Norway, Switzerland, South Africa and others. 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.
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%.  GATT organized a total of eight cycles during which countries exchanged tariff concessions and reduced tariffs. 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. The sixth round of GATT multilateral trade negotiations, which took place from 1964 to 1967. It was named after U.S. President John F. Kennedy in recognition of his support for the reformulation of the U.S.

NAFTA has two complements: the North American Environmental Cooperation Agreement (NAAEC) and the North American Worker Cooperation Agreement (NAALC).
