Pakistan has promised to share with Japan the findings of an ongoing internal investigation into illegal transfers of nuclear technology to North Korea.
Pakistani President Pervez Musharraf made the commitment in a meeting with visiting Japanese Deputy Foreign Minister Ichiro Fujisaki.
In an official statement issued after the meeting, Mr. Musharraf is quoted as telling the Japanese diplomat that Pakistan is still investigating illicit transfers of nuclear technology to North Korea, and the results will be shared with Tokyo when the process is concluded.
As President Musharraf put it, the investigations have exposed the complicity of a few individuals with the nuclear black market, and appropriate action is being taken against them. He reiterated that Pakistan is a responsible nuclear power and is committed to non-proliferation.
Pakistan began questioning some of its top scientists in November after it was warned by the U.N. International Atomic Energy Agency of possible nuclear leaks.
The investigation has already resulted in the public confession by Abdul Qadeer Khan, the creator of Pakistan's nuclear program, that he was involved in illegally selling nuclear secrets to Iran, Libya and North Korea.
Last week, the scientist went on national television to apologize for his actions. He asked for clemency, which President Musharraf has granted him. But Mr. Khan is being guarded under tight security at his house in Islamabad.
Six other scientists and security officials are still under investigation.
Both Iran and North Korea have denied receiving nuclear technology from the top Pakistani scientist. North Korea dismisses the Pakistani scientist's confession, calling it propaganda by the United States.
