Eminent US lawmakers have said Pakistan has gained atomic capabilities through “international deception” and “clandestine procurement” networks. They warned that the continuation of 'secretive' Sino- Pak nuclear ties is setting a wrong precedence for others. Similar networks are now seen on behalf of other states that are either trying to develop nuclear weapons or have done so illegally, said Congressman Brad Sherman at a Congressional hearing. These proliferation techniques need countries to be the transshipment hub in the supply chain. Sherman said technology and equipment from companies in countries with high-tech manufacturing can then go to those hub countries and then on to the prohibited country. He alleged that these hub countries have weak or non-existent export controls, ineffective customs and law enforcement officials and most importantly, little or no political will to do anything about this critical problem. The Congressman said the US experience with Pakistan's nuclear programme demonstrated that export control laws will be of little value unless the US can properly control the flow of global cargo at transshipment hubs.Congressman Ed Royce said China now appears determined to sell Pakistan two nuclear reactors and that's certainly against the norms of the nuclear suppliers group.
