"The U.S.-Mexico bilateral economic relationship is of key interest to the United States because of Mexico's proximity, the extensive cultural and economic ties between the two countries, and the strong economic relationship with Mexico under the North American Free Trade Agreement (NAFTA). The United States and Mexico share many common economic interests related to trade, investment, and regulatory cooperation. The two countries share a 2,000-mile border and have extensive interconnections through the Gulf of Mexico. There are also links through migration, tourism, environmental issues, health concerns, and family and cultural relationships."
