Macau also spelled Macao is, along with Hong Kong, one of the two special administrative regions of the People's Republic of China. It lies on the western side of the Pearl River Delta, bordering Guangdong province to the north and facing the South China Sea to the east and south. The territory's economy is heavily dependent on gambling and tourism but also includes manufacturing. Macau was a Portuguese colony and both the first and last European colony in China. Portuguese traders first settled in Macau in the 16th century and subsequently administered the region until the handover on 20 December 1999.
