Since 1948–2016, the United States has provided nearly US$78.3 billion (adjusted to 2016 value of dollar) to Pakistan in grants annually in forms of military aid (which amounts to 96% of collective US aid). Of these aid and funds arrangement, Pakistan was obligated to spend these monetary funds by purchasing American goods, food, and other services. In spite of China being the largest importer and exporter for Pakistan's market, the United States continues to be one of the largest sources of foreign direct investment in Pakistan and is Pakistan's largest export market.
