Expressing concern over the continuing buildup of nuclear weapons in South Asia, the United States has asked India and Pakistan to restrain their atomic and missile programmes and play a positive role in the global non-proliferation community.
Assistant Secretary of State for International Security and Non-Proliferation Thomas Countryman said.
Continued instability in Pakistan could impact safety of its nuclear weapons and materials, a latest US Congressional report has said as it described the sale of two nuclear reactors by China to Pakistan a violation of the NSG guidelines.
