The Macau Special Administrative Region (MSAR) of the People's Republic of China is a territory located on the western side of the Pearl River Delta in East Asia. Formerly a Portuguese overseas territory, it was the first and last European colony in East Asia, with Portuguese traders first settling in the region in the 1550s. Sovereignty was transferred to China on December 20, 1999, under the "one country, two systems" principle, which guarantees the territory a high degree of autonomy in all matters except defense and foreign affairs for a period of at least 50 years. This arrangement allows Macau to maintain its own executive, legislative, and independent judicial powers, as well as its own currency and immigration policies.

The national flag of Macau features a light green field with a white lotus flower above a stylized bridge and water, all beneath an arc of five gold, five-pointed stars. The stars mirror those on the flag of the People's Republic of China, symbolizing the relationship between the SAR and the central government. The lotus is the floral emblem of Macau, representing the territory's three main parts: the Macau Peninsula, Taipa, and Coloane. The bridge and water signify the territory's geography and its historical role as an important port. Adopted in 1993 and first flown at the handover in 1999, the flag serves as a distinct symbol of the region's administrative identity within China.

The government of Macau is executive-led, headed by a Chief Executive who is appointed by the Central People's Government after being elected by a 400-member Election Committee. The Chief Executive serves a five-year term and is limited to two consecutive terms. Legislative power is vested in the Legislative Assembly, a unicameral body currently composed of 33 members: 14 directly elected by the public, 12 indirectly elected by functional constituencies (representing various social and economic sectors), and 7 appointed by the Chief Executive. The legal system is based on Portuguese civil law, providing a distinct framework from the mainland’s socialist legal system, with the Court of Final Appeal serving as the highest local court.
