Libyan Arms Designs Traced Back to China (washingtonpost.com): "Libyan Arms Designs Traced Back to China
Pakistanis Resold Chinese-Provided Plans
Investigators have discovered that the nuclear weapons designs obtained by Libya through a Pakistani smuggling network originated in China, exposing yet another link in a chain of proliferation that stretched across the Middle East and Asia, according to government officials and arms experts.
The bomb designs and other papers turned over by Libya have yielded dramatic evidence of China's long-suspected role in transferring nuclear know-how to Pakistan in the early 1980s, they said. The Chinese designs were later resold to Libya by a Pakistani-led trading network that is now the focus of an expanding international probe, added the officials and experts, who are based in the United States and Europe.
The packet of documents, some of which included text in Chinese, contained detailed, step-by-step instructions for assembling an implosion-type nuclear bomb that could fit atop a large ballistic missile. They also included technical instructions for manufacturing components for the device, the officials and experts said.
'It was just what you'd have on the factory floor. It tells you what torque to use on the bolts and what glue to use on the parts,' one weapons expert who had reviewed the blueprints said in an interview. He described the designs as 'very, very old' but 'very well engineered.'
U.S. intelligence officials concluded years ago that China provided early assistance to Pakistan in building its first nuclear weapon -- assistance that appeared to have ended in the 1980s. Still, weapons experts familiar with the blueprints expressed surprise at what they described as a wholesale transfer of sensitive nuclear technology to another country. Notes included in the package of documents suggest that China continued to mentor Pakistani scientists on the finer points of bomb-building over a period of several years, the officials said."
