ISLAMABAD (Agencies) - A US decision to suspend $800 million in military aid will not affect Pakistani army operations, its spokesman said Monday, but analysts say the move is likely to fray ties and could harm the countrys economy. White House Chief of Staff William Daley confirmed on Sunday a New York Times report that the Obama administration had held off a third of $2 billion in security aid in a show of displeasure over Pakistans cutback of US military trainers, limits on visa for US personnel and other bilateral irritants. The United States provides hundreds of millions of dollars a year to reimburse Pakistan for deploying more than 100,000 troops along the Afghan border to combat militant groups. Other funding covers training and military hardware. The White House announcement puts $300 million in reimbursement and another $500 million in aid in question. The tribal operations wont be affected by the loss of US assistance, said Pakistans military spokesman, Major-General Athar Abbas. We can conduct our operations without external support. Some of the assistance, he said, was reimbursement for money already spent on several operations on the Afghan border rather than money for future operations. I dont think there will be any significant impact from this, he added. Politically, however, it would be damaging to the relationship, said Pakistans former ambassador to the United States, retired major-general Mehmood Durrani said, reflecting a widespread view in Pakistan that it was fighting Americas war, for which Washington must reimburse it. This is something that they have to pay, and if they dont then its breach of agreement and breach of trust, he said. Holding back the $800 million in aid is unlikely to pressure Pakistan to increase cooperation with the US and could strengthen those in the government who argue that Washington is a fickle ally who cant be trusted, analysts said.
