How China Recruits Spies, Revealed Through Arrest Cases.
July 15, 2016.
Among well-known Chinese spies arrested in the United States, three stand out: Wu-Tai Chin, Kuo Tai-Shen, and Glenn Duffie Shriver.
Through these three cases, the methods by which the Chinese government recruits and utilizes spies have come to light.
The U.S. magazine The National Interest reported on this.
Wu-Tai Chin: Forty Years as a Spy.
According to the magazine, Wu-Tai Chin was recruited by Chinese Communist intelligence in 1949, before the founding of the People’s Republic of China, while he was serving as an official at the U.S. Embassy stationed in the Republic of China.
For the forty years until his arrest in 1985, he provided reports to Chinese intelligence agencies.
During this period, Wu worked as an interpreter for multiple U.S. government agencies, including serving as an interrogation interpreter for prisoners of war with U.S. forces in Korea.
It is said that Chinese intelligence paid Wu a total of one million dollars.
Wu secretly entered China via Hong Kong to meet his handlers and receive payments.
The method involved first sending a letter to a hotel room in Hong Kong, after which Chinese officials would dispatch personnel to meet Wu and collect documents.
Kuo Tai-Shen: A Naturalized American of Taiwanese Origin Recruited During a Trip to China.
Kuo Tai-Shen, a naturalized U.S. citizen, worked as a sales representative at a furniture store in Louisiana.
During a business trip to China in the 1990s, he was recruited by Chinese intelligence.
Although Kuo had contacts with Taiwanese political figures through family connections, he did not have direct access to U.S. government information.
He was encouraged to approach the U.S. Department of Defense and succeeded in recruiting Greg Bergersen and James Fondren as Chinese spies.
Fondren, who served as acting director of the Washington liaison office of U.S. Pacific Command, passed information on U.S. policy to China through Kuo.
Bergersen, an analyst at the Department of Defense, provided Kuo with classified information regarding U.S. arms sales to Taiwan.
Kuo’s superiors met with him inside China or contacted him through intermediaries and email.
Kuo was arrested in 2008.
