Pakistan has rubbished the new dossier on the proliferation network of its disgraced nuclear scientist, saying it is based on 'false information' and A Q Khan sold nuclear technology on his own.

"The sale of nuclear technology was purely his own action and it had nothing to do with the state," Pakistan Defence Spokesman Major General Wahid Arshad said reacting to the dossier by leading London-based think tank International Institute of Strategic Studies.

He claimed the dossier was based on false information.

Several countries, including EU and India, also had proven links with the nuclear black market, he alleged.

The spokesman claimed that Pakistan scientists, engineers and experts have the capability to upgrade nuclear technology domestically as per the needs of the country without the assistance of any black market.

Pakistan Foreign Office spokesperson Tasnim Aslam said the dossier has 'nothing new' to warrant a comment.

"This is like many other studies in the past," she was quoted in the media in Islamabad as saying.

She claimed that Pakistan had taken a number of measures, including establishing a robust command and control structure and export controls that has been acknowledged by the dossier.

The dossier said that Khan clandestinely provided Iran with centrifuges, technical designs, components and an 'address book' of suppliers, which helped Tehran to make significant advances in its secret nuclear programme.

"Khan probably had some signal, if not explicit permission, from his superiors for nuclear cooperation with Iran," the dossier said.
