Earlier this month, a Chinese citizen, Chi Tong Kuok, was convicted in an American court of attempting to obtain American encryption equipment so that China could figure out how to penetrate American government and military coded communications. Kuok admitted these were his instructions from Chinese intelligence, which included a list of 43 specific items to obtain. Kuok was caught when, four years ago, U.S. intelligence discovered him emailing employees of American defense companies, seeking one of those 43 items. Kuok was then contacted by an FBI agent masquerading as a broker for the kind of stuff Kuok was looking for. After that, the evidence piled up, Kuok was arrested and, faced with all that evidence, decided to cooperate a bit.
