The government of the People's Republic of China is based on a system of people's congress within the parameters of a unitary communist state, in which the ruling Chinese Communist Party (CCP) enacts its policies through people's congresses. This system is based on the principle of unified state power, in which the legislature, the National People's Congress (NPC), is constitutionally enshrined as "the highest state organ of power." As China's political system has no separation of powers, there is only one branch of government which is represented by the legislature. The CCP through the NPC enacts unified leadership, which requires that all state organs, from the Supreme People's Court to the State Council of China, are elected by, answerable to, and have no separate powers than those granted to them by the NPC. By law, all elections at all levels must adhere to the leadership of the CCP. The CCP controls appointments in all state bodies through a two-thirds majority in the NPC. The remaining seats are held by nominally independent delegates and eight minor political parties, which are non-oppositional and support the CCP. All government bodies and state-owned enterprises have internal CCP committees that lead the decision-making in these institutions.
The NPC meets annually for about two weeks in March to review and approve major new policy directions, and in between those sessions, delegates its powers to the working legislature, the NPC Standing Committee (NPCSC). This organ adopts most national legislation, interprets the constitution and laws, and conducts constitutional reviews, and is headed by the chairman, one of China's top officials. The president is a ceremonial office and has no real power but represents China abroad, though since the 1990s, the presidency has always been held by the leader of the Chinese Communist Party. Elected separately by the NPC, the vice president has no power other than what the president bestowed on them but assists the president. The head of the State Council, the NPC's executive organ, is the premier. The General Secretary of the Chinese Communist Party is China's leading official since the CCP is tasked with formulating and setting national policy which the state, after being adopted by the NPC or relevant state organ, is responsible for implementing.
