ISLAMABAD: The Foreign Office on Sunday expressed 'surprise' at the Indian government's disappointment over the United States' decision to sell eight F-16 fighter jets to Pakistan.

A 'disappointed' India on Saturday summoned the US envoy in New Delhi, Richard Verma, to 'convey its displeasure' regarding the Obama administration's decision to notify the sale of the aircraft to Pakistan.

Indian Foreign Secretary S Jaishankar met the US ambassador at the ministry to convey India's disapproval of the deal to Washington, in a meeting which lasted 45 minutes.

The $699 million deal consists of eight Lockheed Martin F-16 fighter jets, along with training, radar and other equipment.

The F-16 aircraft will allow the Pakistan Air Force to operate in all kinds of weather, at night, as well as "enhance Pakistan's ability to conduct counter-insurgency and counterterrorism operations," the US Defence Security Cooperation Agency, which coordinates such foreign arms sales, said in a statement.

The proposed deal will now go through a 30-day notification period after which it will be finalised.

The new aircraft will add to Pakistan’s sizable force of fighter jets which includes more than 70 F-16s and dozens of French and Chinese attack aircraft.

Earlier in January, Defence Minister Khawaja Asif during a National Assembly briefing told lawmakers that an Indian lobby, as well as Pakistan's former ambassador to the US are "working against us" and had approached the US House of Representatives to lobby against the sale of the fighter jets, causing a delay.
