WASHINGTON - The United States has indicated it will not oppose Chinas building of two nuclear reactors in Pakistan, and will give Beijing a pass on its non-proliferation commitments by allowing the deal to go ahead in spite of concerns that it will violate international guidelines governing nuclear trade. Last week, the International Atomic Energy Agency (IAEA) gave its approval to a safeguards agreement for two new reactors that China is building at Chashma. The deal, many countries say, goes against Chinas commitments as a member of the Nuclear Suppliers Group (NSG), which bans the sale or transfer of technology to countries that have not signed the NPT. US Assistant Secretary for South and Central Asian Affairs Robert Blake told journalists here he did not bring up the deal during talks with Chinese officials this week on South and Central Asia. While he reiterated the US view that the deal was inconsistent with Chinas NSG commitments, he also mounted a defence of the need for the deal in a briefing with reporters, linking it to an energy crisis and instability in Pakistan. What Id like to emphasise is that its very important that, on the one hand, China observe its NSG obligations, but on the other hand, the international community do as much as possible to help Pakistan to meet its energy needs, Mr Blake said. Pakistan is facing quite severe energy shortages in many parts of the country. So the US has been, I think, in the lead in many cases in trying to help Pakistan to deal with those challenges, and to not only refurbish some of its existing capacity...but to look at new ways to help meet those energy challenges. But those remain a very considerable challenge in Pakistan, and that will be one of our highest priorities, going forward.
