The North American Free Trade Agreement (NAFTA), in effect since January 1994, plays a very strong role in the bilateral economic relationship between Mexico and the United States. The two countries are also closely tied in areas not directly related to trade and investment such as security, environmental, migration, and health issues. The effects of NAFTA on Mexico and the Mexican economic situation have impacts on U.S. economic and political interests. A number of policymakers have raised the issue of revisiting NAFTA and renegotiating parts of the agreement. Some important factors in evaluating NAFTA include the effects of the agreement on Mexico and how these relate to U.S.-Mexico economic relations.

Implementation of the agricultural provisions of the North American Free Trade Agreement (NAFTA) has drawn to a close. In 2008, the last of NAFTA’s transitional restrictions governing U.S.-Mexico and Canada-Mexico agricultural trade were removed, concluding a 14-year project in which the member countries systematically dismantled numerous barriers to regional agricultural trade. During the implementation period, the agricultural sectors of Canada, Mexico, and the United States have become much more integrated.

Over the last decade, the economic relationship between the United States and Mexico has strengthened significantly. The two countries continue to cooperate on issues of mutual concern. President Barack Obama met with Mexican President Calderón and Canadian Prime Minister Harper at the North American Leaders’ Summit in Guadalajara, Mexico, in August 2009 to discuss key issues that affect the three countries. They agreed to continue cooperation in North American competitiveness and security.

U.S. trade agreements such as the North American Free Trade Agreement (NAFTA), World Trade Organization agreements, and bilateral free trade agreements (FTAs) have been approved by majority vote of each house rather than by two-thirds vote of the Senate — that is, they have been treated as congressional-executive agreements rather than as treaties.
