The funds are part of a so-called Coalition Support Fund (CSF), a U.S. program to reimburse countries that have incurred costs supporting counter-terrorism and counter-insurgency operations.

“Pakistan should receive $300 million soon,” said a Pakistani finance official who declined to be identified.

The United States has reimbursed Pakistan $7.4 billion under the CSF program since 2001, when Pakistan joined the U.S.-led campaign against militancy. Funds that come in through the CSF are not officially designated as U.S. foreign aid.
