From the Introduction: "Congress has maintained interest in Mexico, a neighboring country and top trading partner with which the United States has a close but complex relationship. In recent decades, U.S.-Mexican relations have improved as the countries have become close trade partners and worked to address crime, migration, and other issues of shared concern. Nevertheless, the history of U.S. military and diplomatic intervention in Mexico and the asymmetry in the relationship has continued to provoke periodic tension. For example, the U.S. investigation into and October 2020 arrest of Mexico's former defense minister damaged trust between the two governments. Congress remains concerned about the effects of organized-crime-related violence in Mexico on U.S. security interests and about U.S. citizens' safety in Mexico, and it has increased oversight of U.S.-Mexican security cooperation. Congress may continue to appropriate foreign assistance for Mexico and oversee bilateral efforts to address illegal drug flows, unauthorized migration, environmental issues, and the Coronavirus Disease 2019 (COVID-19) pandemic. Implementation of the United States-Mexico-Canada Free Trade Agreement (USMCA) and its labor commitments, Mexico's treatment of U.S. energy firms, and border environmental and water issues may receive oversight attention. This report provides an overview of political and economic conditions in Mexico, followed by overviews of selected issues of congressional interest in Mexico: security and foreign aid, extraditions, human rights, trade, migration, energy, border environmental, water, and health."
