Hong Kong, a Special Administrative Region of the People's Republic of China, can be geographically divided into three territories: Kowloon, Hong Kong Island, and the New Territories. Hong Kong is a coastal city and major port in Southern China, bordering Guangdong province through the city of Shenzhen to the north and the South China Sea to the west, east and south. Hong Kong and its 260 territorial islands and peninsulas are located at the mouth of the Pearl River Delta. The area of Hong Kong is distinct from Mainland China, but is considered part of "Greater China".
