Peru–United States relations
diplomatic relations between the Republic of Peru and the United States of America
The Republic of Peru and United States of America (USA) established relations following Peru's independence from Spain in 1826. In the twenty-first century the two countries have become close partners, collaborating in trade with a free trade agreement and in limiting the trafficking of narcotics into the United States.
Both countries are part of the Asia-Pacific Economic Cooperation forum, as well as the Organization of American States.
History
Nineteenth century
Peru's independence was recognized by the United States by the appointment of James Cooley as Charge d’Affaires on May 2, 1826.
In 1836 Peru joined the Peru-Bolivian Confederation. The United States recognized the Peru-Bolivian Confederation on March 16, 1837 by the appointment of James B. Thornton as Chargé d’Affaires. Thornton was commissioned to Peru but received by the Peru-Bolivian Confederation. Succeeding Thornton, who died in Peru in January, 1838, J.C. Pickett was appointed Charge d’Affaires on June 8, 1838. He did not present his credentials until January, 1840. This lapse in diplomatic representation may be attributed to the dissolution of the Peru-Bolivian Confederation in 1839.
