There are technically two separate commissions; the Central Military Commission of the Chinese Communist Party and the Central Military Commission of the People's Republic of China. Under the arrangement of "one institution with two names", both commissions have identical personnel, organization and function, and operate under both the party and state systems. The commission's parallel hierarchy allows the CCP to supervise the political and military activities of the PLA, including issuing directives on senior appointments, troop deployments and arms spending.
