Ministry of State Security (China)

The Ministry of State Security (MSS), or Guoanbu , is the intelligence, security and secret police agency of the People’s Republic of China (non-military area of interests), responsible for counter-intelligence, foreign intelligence and political security. MSS has been described as one of the most secretive intelligence organizations in the world. It is headquartered in Beijing.The MSS was preceded by the Central Investigation Department (CID), which was China’s primary intelligence organization from 1955 to 1983. The MSS was created in 1983 with the merging of the CID and the counter-intelligence elements of the Ministry of Public Security of the People’s Republic of China.The network of state security bureaus and the Ministry of State Security should not be confused with the separate but parallel network of public security bureaus, administered by the Ministry of Public Security.
The logo of the MSS is unique among Chinese government agencies as it displays the party emblem instead of the state emblem.
