The first important development is the replacement of the General Agreement on Tariffs and Trade (GATT) by the World Trade Organization (WTO) following the conclusion of the Uruguay Round in 1995. The WTO is a much more developed international institution than its predecessor, which has a broader role, which includes not only the implementation of the commitments made by Member States during the Uruguay Round, but also a relatively sophisticated judicial system, called the `dispute settlement procedure`. The agreement opened the door to open trade by ending tariffs on various goods and services and implementing equality between Canada, America and Mexico. NAFTA has allowed tariff exemption for agricultural products such as eggs, maize and meat. This has allowed companies to act freely and import and export different products at the North American level. Compared to the total GDP of its members, the trading bloc is the largest in the world since 2010. NAFTA has two complements: the North American Environmental Cooperation Agreement (NAAEC) and the North American Worker Cooperation Agreement (NAALC). The goal of NAFTA was to remove trade and investment barriers between the United States, Canada and Mexico. Asia-Pacific Economic Cooperation (APEC) is a forum for 21 peripheral Pacific countries (officially members) to promote free trade and economic cooperation throughout the Asia-Pacific region. Created in 1989 to address the growing interdependence of Asia-Pacific economies and the emergence of regional economic blocs (such as the European Union) in other parts of the world, APEC is working to raise living and education through sustainable economic growth and to promote a sense of community and appreciation of common interests between Asian and Pacific countries. Trade agreements are generally unilateral, bilateral or multilateral.
U.S. tariffs are at their lowest in history. Before the Second World War, they were up to 40% for some imports. Today, customs revenues account for less than 5% of the volume of imports and the dollar, and many imports are exempt from tariffs and quotas.
