Pakistan on Sunday rejected Indian concerns over its proposed deal with the United States to buy eight F-16 fighter jets, saying it was surprised by the reaction from New Delhi.
"We are surprised and disappointed at the Indian governments reaction," the Foreign Ministry said in the capital Islamabad. "They are the largest importer of defence equipment."
India summoned the US ambassador to Delhi on Saturday to convey its "disappointment and displeasure" over Washington's plan to sell fighter jets to Pakistan.
"We disagree with their rationale that such arms transfer help to combat terrorism," the Indian Foreign Ministry said.
Islamabad said the deal was to enhance its capability to fight against Islamist militants.
"Pakistan and the United States closely cooperate in countering terrorism ... the sale is to enhance precision strike capability," the statement added.
The proposed 700-million-dollar deal would include Lockheed Martin F-16s, radar, training and logistics support, the US Defense Security Cooperation Agency said on Friday.
Nuclear-capable South Asian neighbours India and Pakistan have fought three wars since their independence from Britain in 1947.
