The United States described the granting of waiver to India by the Nuclear Suppliers Group as a ‘landmark decision’ for strengthening the non-proliferation regime and tackling the global challenge of clean energy.

It was an ‘important moment’ for strengthening the global non-proliferation regime, John Rood, the US acting Under Secretary of State for Arms Control, said after the 45-nation nuclear cartel adopted a India-specific waiver to allow it to start nuclear commerce with the international community.

He said the ‘very important’ statement issued by External Affairs Minister Pranab Mukherjee on Friday, which spoke of India's commitment towards strengthening the non-proliferation system, played a major role in discussions at the NSG.

Rood said it was a ‘critically important’ moment for meeting the energy needs of India and tackling the global challenge of ensuring clean energy.

Members of the NSG approached the issue in a serious manner, he said.

"Countries had particular concerns, particular historical experience" but they approached the issue with the required ‘constructive and cooperative’ attitude,” Rood added.

He appreciated the NSG members for their willingness to approach the dialogue in a manner in which ‘even with regard to most serious concerns, there was willingness to find a way, to reach a kind of compromise that is necessary in multilateral negotiations.’
