WASHINGTON The United States, which has a nuclear deal with India, has decided to object to an agreement under which state-owned Chinese companies would supply Pakistan with two nuclear reactors, The Washington Post reported Tuesday. Citing US officials, the newspaper said the Sino-Pakistan agreement is expected to be discussed next week at a meeting in New Zealand of the 46-nation Nuclear Suppliers Group, which monitors such transactions. The Post noted that experts had taken the view that the agreement appears to be a violation of international guidelines forbidding nuclear exports to countries that have not signed onto the nuclear Non-Proliferation Treaty (NPT) or do not have international safeguards on reactors. Pakistan has not signed the treaty. China has suggested the sale is grandfathered from before it joined the NSG in 2004, because it was completing work on two earlier reactors for Pakistan at the time, it said. But US officials disagree. Additional nuclear cooperation with Pakistan beyond those specific projects that were grandfathered in 2004 would require consensus approval by the NSG, a US official said, speaking on condition of anonymity, which we believe is extremely unlikely. State Department Spokesman Gordon DuGuid said the US government has reiterated to the Chinese government that the United States expects Beijing to cooperate with Pakistan in ways consistent with Chinese non-proliferation obligations. Observers were surprised by the US objection to China-Pakistan agreement. They pointed out that the US deal with India effectively allows New Delhi to expand its nuclear power industry, with US help, without requiring it to sign the Non-Proliferation Treaty (NPT) as other nations must. The US restricted nuclear cooperation with India after it tested a nuclear weapon in 1974. The Indo-US deal also blows a hole in US and global non-proliferation rules. The legislation allows India-specific waivers to US laws designed to prevent the misuse of US nuclear technology to build weapons, as India did in the 1970s.
