Cox Report

This special committee, created by a 409–10 vote of the U.S. House of Representatives on June 18, 1998, was tasked with the responsibility of investigating whether technology or information was transferred to the People's Republic of China that may have contributed to the enhancement of the nuclear-armed intercontinental ballistic missiles or to the manufacture of weapons of mass destruction.

While several groups, including the People's Republic of China, contend that the Report is overstated or inaccurate, its authors and supporters maintain that its gist is undeniable.

The report's basic findings were as follows, quoted from the above document's opening summary: The People's Republic of China (PRC) has stolen design information on the United States' most advanced thermonuclear weapons.

The Select Committee judges that the PRC's next generation of thermonuclear weapons, currently under development, will exploit elements of stolen U.S. design information.

At the same time, no person has ever been convicted of providing nuclear information to the PRC, and the one case that was brought in connection to these charges, that of Wen Ho Lee, fell apart.
