In another speech to the Conference on Disarmament, Pakistan's Foreign Minister Assef Ahmad Ali sought "categorical assurances" from India it would not carry out a nuclear test. 28 March 1996 (Reuter) - Hong Kong Nuclear Investment Co Ltd (HKNIC) confirmed in a statement that shutdowns at its Daya Bay nuclear plant in China would be staggered and would not affect power supply to its customers. The shutdown of the twin 900 megawatt reactors, primarily for maintenance and repairs, would have no nuclear safety impact, it said. 28 March 1996 (Reuter) - Washington's curbs on exports of nuclear equipment to China have hobbled U.S. firms in the international race for a share of Beijing's ambitious atomic energy build-up, executives said. U.S. nuclear firms face a long-standing congressional restriction on dealings with China, and current Sino-U.S. tensions over Taiwan, trade and nuclear proliferation make it unlikely the situation will change soon.
