ChinaChinaGovernment & politics
ChinaChina
China is a one-party state led by the Communist Party of China (CPC). Formal state institutions — the presidency, the Premier and the National People's Congress — operate under the direction of the Party. Ultimate power rests with the Party's General Secretary, who typically also holds the state presidency and chairs the Central Military Commission, concentrating Party, state and military authority in one person. The National People's Congress is the constitutional legislature but functions largely to ratify Party decisions rather than to check them.
South Korea
South Korea is a presidential republic. The directly elected President is both head of state and government and serves a single five-year term with no re-election — a rule designed to prevent the concentration of power seen under earlier authoritarian rule. A Prime Minister, appointed by the President, assists but does not lead the government. The unicameral National Assembly makes the laws, and a powerful Constitutional Court can remove a president through impeachment.
