The US has delivered over USD 633 million to Pakistan as part of its ongoing commitment to the country's "national defence" and the joint effort in the fight against violent extremist groups.
The funding from the Coalition Support Fund was delivered to the Pakistan government on Wednesday, the US embassy spokesman Alberto Rodriguez said.
The sum of over USD 633 million had been given to Pakistan as part of the US' commitment to the country's "national defence and the joint effort in the fight against violent extremist groups," he said.
The Coalition Support Fund is designed to reimburse Pakistan for expenses incurred in fighting militants.
The Pakistan government expends hundreds of millions of dollars annually in this effort, Rodriguez said.
The latest reimbursement covers the period from January to June, he said.
A sum of 110 million dollars was previously released in early November to finalise reimbursement of claims made for 2009, he said.
Since 2001, the US has reimbursed Pakistan approximately USD 8.76 billion from the Coalition Support Fund.
Reports have said that the US had held up several payments claimed by Pakistan from the Coalition Support Fund due to problems uncovered during audits by American authorities.
The issue had become an irritant in bilateral ties in recent months.
However, Rodriguez said the US "strives to make reimbursements in as timely manner as possible."
The Coalition Support Fund process reimburses 27 countries, including Pakistan, for logistical, military and other support provided to the US in its overseas contingency operations.
