Pakistan yesterday ruled out any change in its “dynamic” policy of increasing its nuclear weapons, as it dismissed the US' request in this regard, citing India's military modernisation.

A day after Secretary of State John Kerry asked Pakistan to review its policy of increasing its nuclear weapons stockpile, Sartaj Aziz, foreign affairs advisor to the Prime Minister, conceded that the nuclear issue was one of the areas of differences between the US and Pakistan.

"Globally, all the international agencies and the US have acknowledged that Pakistan has developed a very good system for the safety for export control, and command and control system," Aziz said during an interaction at the Council on Foreign Relations.
