The Central Commission for Discipline Inspection (CCDI) is the highest supervisory organ of the Chinese Communist Party (CCP). The CCDI is elected and supervised by the CCP National Congress. It is tasked with defending the party constitution, enforcing inner-party regulations, coordinating anti-corruption work, and safeguarding the core position of the CCP general secretary Xi Jinping and the party as a whole. Safeguarding the political position of Xi and the Central Committee is, officially, the CCDI's highest responsibility. Since the vast majority of officials at all levels of government are also CCP members, the commission is, in practice, the top anti-corruption body in the People's Republic of China (PRC).
At its first plenary session after being elected by a CCP National Congress, the CCDI elect its secretary, deputy secretaries, secretary general and other Standing Committee members. The CCDI then reports the election results to the Central Committee, which can either approve or disapprove of the results. The CCDI Standing Committee is responsible for convening and presiding over plenary sessions of the CCDI. When the CCDI is not in session, its powers and responsibilities are delegated to the CCDI Standing Committee, which has to implement the decisions of the CCP Central Committee and the CCDI plenary sessions. It is held accountable to the CCDI plenary sessions. The secretary convenes, presides over the work and sets the agenda of the CCDI Standing Committee meetings. The current secretary is Li Xi, who was elected by the 1st Plenary Session of the 20th Central Commission for Discipline Inspection and approved by the 20th Central Committee on 23 October 2022.
