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.
Japan
Japan is a constitutional monarchy in which the Emperor is defined by the postwar constitution as the 'symbol of the State' with no governing power at all. Executive authority lies with the Prime Minister, chosen by and accountable to the elected House of Representatives, and the Cabinet. Japan's constitution famously renounces war, and the military (the Self-Defense Forces) is under strict civilian control.
