From the Introduction: "The 116th Congress has demonstrated renewed interest in Mexico, a neighboring country and top trading partner with which the United States has a close, but complicated relationship. [...] In recent decades, U.S.-Mexican relations have improved as the countries have become close trade partners and worked to address crime, the environment, and other issues of shared concern. Nevertheless, the history of U.S. military and diplomatic intervention in Mexico and the asymmetry in the relationship continue to provoke periodic tension. As the United States-Mexico-Canada Free Trade Agreement (USMCA), approved by Congress in January 2020, enters into force on July 1, 2020, its implementation is likely to receive congressional attention. Congress remains concerned about the effects of organized-crime-related violence in Mexico on U.S. security interests and U.S. citizens' safety in Mexico and has increased oversight of U.S.-Mexican security cooperation. Congress may appropriate foreign assistance for Mexico and oversee bilateral efforts to address U.S.-bound unauthorized migration, illegal drug flows, and the Coronavirus Disease 2019 (COVID-19) pandemic. This report provides an overview of political and economic conditions in Mexico, followed by assessments of selected issues of congressional interest in Mexico: security and foreign aid, extraditions, human rights, trade, migration, energy, water, and environmental issues at the border."
