KARACHI (Reuters) Pakistan received on Wednesday $349.3 million from the United States as part of a fund to help the US ally sustain efforts to fight militancy, a central bank official said on Wednesday. We have received $349.3 million as reimbursement from the US for the coalition support fund, said Syed Wasimuddin, chief spokesman for the State Bank of Pakistan. The US fund is used to reimburse states such as Pakistan that have incurred costs in supporting counter-terrorist and counter-insurgency operations. Pakistan had in recent months been complaining that the United States was behind on payments. The United States said there had been some delays for administrative reasons. Last month, President Asif Ali Zardari told US Special Representative for Afghanistan and Pakistan Richard Holbrooke that the war on militancy had cost Pakistan $35 billion in the last eight years. According to official figures, the United States has given Pakistan $15.4 billion since 2002, about two-thirds security-related and the rest economic aid. That figure does not include the $349.3 million received on Wednesday. Pakistan has been struggling to get its economy back since 2008 when the government agreed to an International Monetary Fund loan of $7.6 billion. The loan was increased to $11.3 billion in July last year.
