Introduction & Background

Hong Kong (/ˈhɒŋkɒŋ/ (US) or /hɒŋˈkɒŋ/ (UK); Chinese 香港, Cantonese: Template:IPA-yue), officially the Hong Kong Special Administrative Region of the People's Republic of China (abbr. Hong Kong SAR or HKSAR),d is a city and special administrative region of China on the eastern Pearl River Delta in South China. With 7.5 million residents of various nationalitiese in a 1,104-square-kilometre (426sqmi) territory, Hong Kong is one of the most densely populated places in the world. Hong Kong is also a major global financial centre and one of the most developed cities in the world.

Hong Kong was established as a colony of the British Empire after the Qing Empire ceded Hong Kong Island from Xin'an County at the end of the First Opium War in 1841 then again in 1842.18 The colony expanded to the Kowloon Peninsula in 1860 after the Second Opium War and was further extended when Britain obtained a 99-year lease of the New Territories in 1898.1920 British Hong Kong was occupied by Imperial Japan from 1941 to 1945 during World War II; British administration resumed after the surrender of Japan.21 The whole territory was transferred to China in 1997.22 As one of China's two special administrative regions (the other being Macau), Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of "one country, two systems".23f
