North Korea received designs for uranium enrichment centrifuges from Pakistan's disgraced nuclear scientist A Q Khan in return for its long-range missiles, a Congressional report has told US lawmakers.
"Hwang Jang-yop, a Communist Party secretary who defected in 1997, has stated that North Korea and Pakistan agreed in the summer of 1996 to trade North Korean long-range missile technology for Pakistani HEU (highly enriched uranium) technology," the report on North Korean nuclear weapons programme has said.
Other information on North Korean-Pakistani cooperation dates back to 1993, said the report by Congressional Research Service (CRS) - the research wing of the US Congress.
North Korea has been exporting missiles to countries in the Middle East and South Asia and has had joint collaboration in development of missiles with Iran and Pakistan, it said.
In the 1990s, North Korea exported Scud and Nodong missiles to Pakistan, Iran, Yemen, Syria and reportedly Egypt. It entered into joint development programmes with both Pakistan and Iran.
Pyongyang received designs for uranium enrichment centrifuges from Pakistan nuclear "czar" A Q Khan and has attempted to purchase overseas key components for uranium enrichment centrifuges, but some of these purchases have been blocked, according to the report.
