The two countries made the announcement Monday following a visit by U.S. Sen. John Kerry to Islamabad. Kerry is the chairman of the Senate Foreign Relations Committee.
Relations between the two countries have been badly strained following the U.S. Navy SEAL raid that killed Osama bin Laden on May 2.
U.S. officials have said they didn't tell Pakistan about the operation before it happened, because they were worried bin Laden might be tipped off.
