A Guide to the United States' History of Recognition, Diplomatic, and Consular Relations, by Country, since 1776: Pakistan
The United States and Pakistan have generally enjoyed a close relationship since Pakistan’s independence in 1947. Pakistan has historically been a supporter of U.S. foreign policy, specifically during the United States’ opening to China and following the Soviet invasion of Afghanistan. For its part, the United States has striven to lessen tensions between Pakistan and India. Although relations between the United States and Pakistan remain somewhat unsettled over regional disputes and Pakistan’s nuclear weapons program, the United States has provided Pakistan with economic aid through loans and debt relief and is a major supplier of military equipment to Pakistan.
