The United States recognized the Government of Buenos Ayres (predecessor of Argentina) on January 27, 1823. Diplomatic relations were briefly interrupted in 1944. The United States and Argentina maintain a bilateral relationship based on shared interests including economic ties, democracy and human rights, counterterrorism and rule of law, improving citizen security, energy, science and technology, people-to-people ties, and education.
U.S. assistance in Argentina promotes regional stability and democracy and builds non-proliferation cooperation on export controls and border security. The United States and Argentina also cooperate on economic revitalization and public security. The International Narcotics and Law Enforcement (INL) Bureau provides funds to the Drug Enforcement Administration (DEA) and the Federal Bureau of Investigation (FBI) to train and mentor Argentine law enforcement and justice officials; this has strengthened the ability of both governments to respond to shared security interests in the Western Hemisphere.
