Washington: Despite the Japanese nuclear disaster, the United States remains committed to its civil nuclear deal with India.

"We remain very much committed to pursuing civil nuclear cooperation with India," US Assistant Secretary of State for South Asia Robert Blake said at a media roundtable in Beijing on Friday.

Asked to clarify US position on the Chinese-Pakistan nuclear deal, he said the US expected China to abide by the commitments that it made when it joined the Nuclear Suppliers Group (NSG) in 2004.

"In particular we think the construction of new nuclear reactors such as the Chasma 3 and 4 would be inconsistent with those commitments," Blake said.

According to a transcript issued by the State Department here, he said the US had been very clear in the NSG context about that position, "but we've also been very clear on the need to support Pakistan's energy development."

Asked if India had expressed its concerns or asked US to do more in regard to the China-Pakistan deal, Blake said, "Not beyond what we've already talked about which is again, to hold Pakistan to its NSG commitments."

"I think that's their principal concern as well. They also understand that Pakistan has severe energy needs and that this affects internal stability and therefore it's important for all countries to help Pakistan meet its own energy needs,” he added.

Asked to comment on suggestions that the US is using India as a hedge against China, Blake said the US "considers India to be probably one of the defining partnerships for us in the 21st century."

"We want to see the growth of our relations with China, our relations with India, and India's relations with China," he said.
