USAID/Pakistan: History of USAID in Pakistan
From a modest beginning in 1951, U.S. bilateral assistance to Pakistan grew to almost $400 million a year in the early 1960s
As the single largest donor ($712 million, or 31 percent of all contributions) to the Indus Basin Development project, the United States played a leading role in the construction of the Mangle and Tarbela dams. The dams continue to make significant contributions to Pakistan’s energy and agricultural sectors today.
The 1982-1987 phase of U.S. assistance to Pakistan was a milestone in U.S.-Pakistan relations. Cooperation between the two countries was close as they negotiated a $1.62 billion program in 1981
About 55 percent of the 1982-87 programs were purely grants, and the remainder consisted of soft loans, or loans with generous repayment terms. Given the generosity of the terms of these loans and the high percentage of grants throughout that period, U.S. assistance was the most concessional of any major donor. The economic assistance program planned for 1988-1993 had even more generous terms
