Pakistani President Pervez Musharraf said in South Korea that his country had never helped North Korea's nuclear weapons programme and would never do so. Musharaff said in a speech in Seoul that reports that Islamabad had traded its nuclear know-how for Pyongyang's missile technology were "aspersions cast against my country". "I have investigated the past and I found no trace of any proliferation," he told a South Korean security think tank. "Let me assure and guarantee this house that there will never be any proliferation and there will never be a transfer of technology in the future," Musharraf said. He earlier told South Korean media that Pakistan had in the past had military cooperation with North Korea and had bought missiles from Pyongyang, which is at the centre of a nuclear proliferation crisis in Northeast Asia, but that had stopped. "We have had relations and defence cooperation with North Korea and we have bought surface-to-air missiles in the past because of a threat to us. But now we produce ourselves," he told the Korea Times. Pakistan has repeatedly denied reports of any nuclear or missile-related co-operation with North Korea. A Pakistani firm was slapped with US sanctions last March for arranging the transfer of nuclear-capable missiles from North Korea to Pakistan. In an interview with the Korea Herald, Musharraf voiced support for six-party talks involving the two Koreas, the United States, China, Russia and Japan aimed at halting North Korea's nuclear arms programme. "We are extremely concerned about the escalation of nuclear tension on the Korean Peninsula," he told the Herald. l Former US President Bill Clinton said yesterday Washington should offer food and energy supplies to North Korea in return for access to its laboratories to help resolve a crisis over the Pyongyang's nuclear programme. "I think we ought to offer them a mega deal," he said. **PHOTO CAPTION*** Pakistani President Pervez Musharraf (L) attends a welcoming ceremony as South Korean President Roh Moo-hyun (R) looks on at the presidential Blue House in Seoul November 6, 2003.
