The two countries share a maritime and land border in North America. Several treaties have been concluded between the two nations bilaterally, such as the North American Free Trade Agreement (NAFTA). Both are members of various international organizations, including the Organization of American States and the United Nations.
The two countries have close economic ties, being each other’s first and third largest trading partners. They are also closely connected demographically, with over one million U.S. citizens living in Mexico and Mexico being the largest source of immigrants to the United Sates. Illegal immigration and illegal trade in drugs and in fire arms have been causes of differences but also of cooperation.
