This CRS report provides an overview of the relationship between the United States and its southern neighbor-Mexico. First of all, the report looks at the most recent developments that have occurred this year. The relationship between the two nations is examined in the following areas: political developments, economic conditions, socio-economic conditions and foreign policy challenges. The report also reviews certain bilateral issues for Congress as well as enacted legislation and additional legislative initiatives. According to the report, "the United States and Mexico have a close and complex bilateral relationship, with extensive economic linkages as neighbors and partners under the North American Free Trade Agreement [NAFTA]. Bilateral relations are generally friendly, although the U.S. enactment of border fence legislation in October 2006 caused some tension in the relationship. Drug trafficking issues are prominent in relations since Mexico is the leading transit country for cocaine, a leading supplier of methamphetamine and heroin, and the leading foreign supplier of marijuana to the United States."
