At the 1994 Summit of the Americas, leaders of democratic nations in the Western Hemisphere committed to establishing a Free Trade Area of the Americas (FTAA) by January 2005. The Declaration of Principles resulting from that Summit called for building on “existing sub-regional and bilateral arrangements in order to broaden and deepen hemispheric economic integration and to bring the agreements together.” Although ambitious, this endeavor was undertaken during a decade marked by an unprecedented proliferation of trade agreements. In 1991, Argentina, Brazil, Paraguay and Uruguay agreed to initiate the formation of a common market now known as the MERCOSUR. Then in 1994, Canada, Mexico and the United States signed the North American Free Trade Agreement which replaced the United States-Canada Free Trade Agreement. Later that year, nations around the world formalized the existing General Agreement on Tariffs and Trade, creating the World Trade Organization. In 1997, the Andean Community of Bolivia, Colombia, Ecuador, Peru and Venezuela formalized its plans to establish a common market. Members of the Caribbean Community and Common Market also agreed in several protocols to further their economic and social integration. During the 1990's, numerous other trade agreements were negotiated, and their development continues at the same rapid pace today.
