Pakistan, he claimed, qualified for the type of arrangements that the United States has made with India. There is still time for rectify the situation and if that is not done, a major opportunity could be lost, Aziz said at Columbia University on Tuesday night.

"As part of our effort to promote international security, Pakistan has offered a Strategic Restraint Regime to India aimed at stabilising nuclear deterrence in South Asia and avoiding an arms race in strategic and conventional weapons," he said.

Pakistan was determined to prevent terrorists and extremists from acquiring weapons of mass destruction or know-how, he said, and claimed a major role for Islamabad in dismantling its former top scientist A Q Khan's network of international nuclear black market.
