ISLAMABAD, Pakistan — In an unusually critical statement, a senior Pakistani official said that Pakistan remained opposed to India’s inclusion in the Nuclear Suppliers Group and feared that the country’s growing nuclear cooperation with the United States could harm deterrence efforts in South Asia.
The statement by Sartaj Aziz, the Pakistani national security adviser, came after President Obama wound up his visit to India, during which the United States and India announced an array of trade and strategic agreements.
Pakistan and India have had an antagonistic relationship since the end of British rule and their partition in 1947. In recent years, Pakistan has viewed growing United States-India cooperation with apprehension.
In addition to Mr. Aziz’s criticism, the Pakistani Army chief, Gen. Raheel Sharif, went to China on Sunday for a two-day visit with political and military leaders. The trip directly coincided with Mr. Obama’s visit in India, and Pakistani news organizations covered the parallel trips prominently — particularly statements by Chinese officials that “Pakistan’s concern is China’s concern.”
“Pakistan is opposed to yet another country-specific exemption from N.S.G. rules to grant membership to India, as this would further compound the already fragile strategic stability environment in South Asia,” Mr. Aziz said Tuesday in the statement. The Nuclear Suppliers Group is a 48-nation body established 40 years ago to ensure that civilian trade in nuclear materials is not diverted for military purposes.
“A country, in violation of United Nations Security Council resolutions on matters of international peace and security, such as the Jammu and Kashmir dispute, by no means qualifies for a special status in the Security Council,” the statement read, referring to the Himalayan region of Kashmir, over which Pakistan and India have fought three wars.
