Even as China chose to remain mum on its plans to build two new nuclear reactors for Pakistan, President Asif Ali Zardari today expressed satisfaction over the Sino-Pak atomic cooperation, notwithstanding reservations from countries like India and the US. On the fourth day of his visit to China which gained prominence with speculation that it would firm up plans to build two 650 MW reactors for Pakistan as a move to counter Indo-US nuclear accord, Zardari said the Chinese gesture reflected the warm and friendly ties between the two countries. The President, who is on his fifth official visit to China since 2008, expressed satisfaction over the cooperation between the two countries in civil-nuclear technology, setting aside reservations of the world community, Pakistan's officialAPP news agency reported, citing his speech at the Pak-China Economic Forum in Beijing. He apparently did not make direct reference to the nuclear reactors but his remarks about reservations by the international community left little doubt, as the US and India have expressed concerns over Beijing's plans two build the two new nuclear reactors. Washington has even sought details from China on how it could build the reactors without the nod of the Nuclear Suppliers Group of which Beijing is a member. In his speech, Zardari, who is in China on a six-day visit, noted that the Pakistan-China friendship was centuries old and stood the test of the time. The Sino-Pak friendship was an important feature for peace and stability in the region, he said, adding both countries had to stand together to fight the new challenges in the region.
