Macau is a special administrative zone of the People's Republic of China, located about 50 kilometers west of Hong Kong. Until 1999 it was a Portuguese colony. Macau is rich in colonial-era attractions. The main sources of earnings are legal gambling and related tourism from Hong Kong and mainland China, so Macau is often also called Monte Carlo of the East or Las Vegas of the East. The city is the seat of the Bishopric of Macau.
The growth of China's middle class and, as a result, tourism have caused a rapid economic boom in Macau. Considered an independent state, Macau would be the fourth largest country in the world in terms of GDP per capita
Judging by the human development index, Macau is one of the most developed countries.
