US Secretary of State Condoleezza Rice plans to press Pakistan President Pervez Musharraf for more information on the help that rogue Pakistani scientist, A.Q. Khan, is believed to have given Iran to develop a nuclear weapons program, a senior administration official has said. Speaking before talks between Rice and Indian and Pakistani leaders on the first leg of her trip to Asia, the official said Pakistan had been helpful in the past on sharing information from its own investigation of Khan, but that the administration wanted more. ‘‘We have been getting good cooperation from the Pakistanis,’’ the official said when asked about the investigation into Iran. ‘‘They have been pursuing this. Of course we always want more. We always discuss non-proliferation with the Pakistanis. I am sure we will discuss it this time. I am sure A.Q. Kahn will come up.’’ The official didn’t specify what sort of information the US wanted. But there is heightened interest in what European and American officials have said was a document recently turned over to international investigators showing that Iran had discussed with Khan’s network the possibility of acquiring nuclear weapons technologies some 18 years ago. A European diplomat said last month that the discussions had included an offer by Khan’s representatives to provide technologies that included the process of casting uranium metal, a critical step toward making a weapon. Other administration officials say they have not been entirely satisfied that Pakistan has told the US everything it knows about Khan’s dealings, and that Pakistan’s refusal to let American investigators talk with him has hampered their investigation.
