The CDSA was thoroughly reorganized in the summer of 1949. It ceased to exist in name, and some of its most prominent officers were transferred to senior positions in the new Ministry of Public Security of the CCP Central Revolutionary Military Affairs Commission (after the founding of the People's Republic of China renamed the Ministry of Public Security of the Central People's Government).
After an extended transition during which segments of the former CDSA came within the purview of the People's Liberation Army, it was fully re-established as an organ directly under the Communist Party Central Committee in 1955, now with the new name Central Investigation Department (CID).
The MSS was established in 1983 as the result of the merger of the CID and the counter-intelligence elements of the Ministry of Public Security of the People's Republic of China.
