Macau (Chinese Superpower)

Macau, officially the Macao Special Administrative Region of the People's Republic of China, is an autonomous territory of China on the western side of the Pearl River estuary in East Asia. Along with Hong Kong, Guangzhou, Shenzhen, Zhuhai, and several other major cities in Guangdong, the territory forms a core part of the Pearl River Delta metropolitan region, the most populated area in the world. With a population of 784,099 in an area of 30.5 km2 (11.8 sq mi), it is the most densely populated region in the world.

Macau was formerly a colony of the Portuguese Empire, after Ming China leased the territory as a trading post in 1557. Originally administered under Chinese authority and sovereignty, Qing China fully ceded the area in 1887. Macau remained under Portuguese control until 1999, when it was returned to China.
