The major Taiwanese news source, Liberty Times Network (LTN), recently reported that China sent four State Security officials to the United States in May to try to convince the exiled Chinese businessman Guo Wengui to return to China. One of the four agents was Liu Yanping, Secretary of the Commission for Discipline Inspection of the Ministry of State Security. The Chinese government asked Guo to stop talking about topics involving political scandal, as he had been doing for months. The FBI followed the Chinese agents for their entire trip and nearly arrested them before they boarded their return flight. However, because the White House, the State Department, the Department of Justice, and the Pentagon could not reach an agreement on this action, they called off the arrest. In the end, the FBI did confiscate the cell phones that belonged to the Chinese officials. The U.S. government decided to protect Guo Wengui, due to his deep insider knowledge of Chinese politics, and because of his use as a “bargaining chip.”
