Deploring the US go ahead to Israel to sell Phalcon early warning radar system to India, Pakistan has said this would affect the delicate strategic balance in South Asia.
"This US decision would only enhance India's arrogance and its intransigence in refusing to resolve differences and stimulate tension in the region," the foreign office said in a statement in Islamabad.
The radar, the statement added, would destabilise the 'existing strategic balance with far-reaching security implications for the region'.
Pakistan also said the US, by its decision, has undermined its own efforts to ease tensions in the region and to promote the peace process.
It said that efforts should have been rather directed towards restoring conventional balance between Pakistan and India.
"This was the key to ensuring peace and security in the region as well as to peaceful resolution of differences between the two countries," the statement said.
"There appear to be inadequate understanding of the situation in the region," it said.
