Hu Liren stated on the "Real China" program that many CCP agents overseas have already been put under surveillance and identified by the intelligence agencies of various countries, including Wang Shujun, Tang Yuanjun, and others who have mixed themselves in among overseas democracy movements.
Tang Yuanjun, a naturalized U.S. citizen and New York resident, has admitted to conspiring to act as an unregistered agent of the Chinese government within the United States, reporting information on overseas pro-democracy activists to the state security (MSS).
On August 21, 2024, the U.S. Department of Justice announced the arrest of former 1989 student movement participant Tang Yuanjun in New York, charging him with acting as an unregistered agent for the Chinese Ministry of State Security, spying on overseas pro-democracy activists, and making false statements.
Since 2018, the Chinese Communist Party (CCP) used Tang Yuanjing's longing for home as a lure of returning to China and successfully turned him.
