A judge in the US District Court for the Eastern District of Virginia on Friday sentenced Tai Shen Kuo, a naturalized US citizen and Louisiana businessman, to 188 months in prison for his part in a conspiracy to deliver national defense information to China. Judge Leonie Brinkema also required Kuo to forfeit $40,000 after he pleaded guilty to the espionage charges on May 13. According to the Department of Justice, between March 2007 and February 2008 Gregg William Bergersen, an analyst at the Defense Security Cooperation Agency, a group within the Department of Defense, gave Kuo classified information on US military sales to Taiwan and US military communications security. The DOJ also stated that Kuo gave gifts to Bergersen and promised to give him a position in his company.

Bergersen was charged and arrested in February and later pleaded guilty to conspiracy for disclosing national defense information. Last month he was sentenced to five years in prison. In another Chinese espionage case, Dongfan "Greg" Chung, a former Chinese-American engineer at Boeing, was arrested in February and charged with stealing corporate trade secrets related to aerospace programs and turning them over to China. Chung's and Bergersen's activities were allegedly linked by Chi Mak, a Chinese-American engineer sentenced in March for conspiring to smuggle sensitive naval intelligence data to China.
