Liu Liankun

Liu Liankun, was a Major General in the People's Liberation Army who provided the Republic of China (ROC) in Taiwan with secret intelligence about the status of missiles from the People's Republic of China (PRC). During the 1996 missile crisis, the ROC Ministry of National Defense notified the public that the missiles launched by the PRC actually carried unarmed warheads. This tipped off Beijing that Taipei had a high-level mole working on the mainland. Liu, a top Chinese military logistics officer, was arrested, court-martialed and executed in 1999.
