The Central Guard Bureau of the General Office of the Chinese Communist Party (Chinese: 中共中央办公厅警卫局), also nominally affiliated with the army and the police as the Guard Bureau of the Joint Staff Department of the Central Military Commission (中央军委联合参谋部警卫局) and the Ninth Bureau of the Ministry of Public Security (公安部九局) respectively, is the organization responsible for the protection of senior party members, their families, and important foreign dignitaries in the People's Republic of China. It has been widely called the Central Guard Bureau (CGB; 中央警卫局) since the Cultural Revolution. The bureau selects and controls the bodyguards of protectees; bodyguards are typically trained by the People's Liberation Army (PLA). The CGB is part of the internal security apparatus as protectees are constantly under surveillance by their bureau-selected bodyguards.
The CGB effectively controls the PLA Ground Force Beijing Garrison's Central Guard Corps (PLA Unit 61889, formerly known as the Central Guard Regiment), an elite security unit, by having bureau deputy directors in leadership positions in the unit.
