Central Social Affairs Department
In 1983, the Investigation Department and other relevant agencies were merged to form the Ministry of State Security (MSS) as its successor.The creation of the Central Social Affairs Department (SAD) followed a decision taken by the Secretariat of the Chinese Communist Party on 18 February 1939.[1] The decision assigned to the department some five major tasks, including those of overseeing CCP counter-intelligence work and intelligence.In 1955, the task of political intelligence work was transferred to a newly created Communist party body, the CCP Central Investigation Department (CID) with Li Kenong as its first director.Worth noting in an institutional history context is the fact that some of the SAD's sub-national counterparts (e.g., the Department of Social Affairs of the CCP Committee of province X) continued to exist as party bodies for quite some time after the founding of the PRC.
