Prime Minister's advisor on Foreign Affairs Sartaj Aziz said that the Congressional blockade may force it to turn to other countries.
"Pakistan will buy F-16s from some other country if funding (from US) is not arranged," Aziz said at a seminar.
The two nations had agreed on USD 700 million deal under which Pakistan was to pay USD 270 million from its national funds to purchase eight F-16s while the US was supposed to finance the rest of the amount from its Foreign Military Financing (FMF) fund.
Earlier, at a Congressional hearing, US lawmakers made it clear that they would not allow the Obama administration to use US funds for the deal.
Last Friday, a State Department official said Congress had placed a hold on the deal, forbidding the administration from using US funds for enabling Pakistan to buy the planes.
And yesterday, the department confirmed that Pakistan will have to use its own funds if it wants the planes.
Aziz said F-16s was an effective tool to fight militancy and it can be replaced by JF-17 Thunder jets, locally produced.
"The international community should avoid steps which may disturb the strategic balance in South Asia," he said.
