A Trade and Investment Framework Agreement (TIFA) is a trade pact that establishes a framework for expanding trade and resolving outstanding disputes between countries. TIFAs are often seen as an important step towards establishing Free Trade Agreements. The GATT The General Agreement on Tariffs and Trade (GATT) is a legal agreement between many countries, whose overall purpose was to promote international trade by reducing or eliminating trade barriers such as tariffs or quotas. According to its preamble, its purpose was the "substantial reduction of tariffs and other trade barriers and the elimination of preferences, on a reciprocal and mutually advantageous basis." The GATT was first discussed during the United Nations Conference on Trade and Employment and was the outcome of the failure of negotiating governments to create the International Trade Organization (ITO). It was signed by 23 nations in Geneva on 30 October 1947, and took effect on 1 January 1948. It remained in effect until the signature by 123 nations in Marrakesh on 14 April 1994, of the Uruguay Round Agreements which established the World Trade Organization (WTO) on 1 January 1995. The WTO is a successor to the GATT, and the original GATT text (GATT 1947) is still in effect under the WTO framework, subject to the modifications of GATT 1994. Nations that were not party in 1995 to the GATT need to meet the minimum conditions spelled out in specific documents before they can accede; in September 2019, the list contained 36 nations. The GATT, and its successor the WTO, have successfully reduced tariffs. The average tariff levels for the major GATT participants were about 22% in 1947, but were 5% after the Uruguay Round in 1999. Experts attribute part of these tariff changes to GATT and the WTO. NAFTA The North American Free Trade Agreement (NAFTA; , TLCAN; , ALÉNA) is an agreement signed by Canada, Mexico, and the United States, creating a trilateral trade bloc in North America. The agreement came into force on January 1, 1994, and superseded the 1988 Canada–United States Free Trade Agreement between the United States and Canada. The NAFTA trade bloc is one of the largest trade blocs in the world by gross domestic product. ASEAN The United States and ASEAN concluded the U.S.-ASEAN Trade and Investment Arrangement (TIFA) in 2006 and since then have been working to build U.S.-ASEAN trade and investment ties as well as promote ASEAN regional
