Hong Kong 香港特別行政區
See separate listing under Hong Kong
Hong Kong was a dependent territory of the United Kingdom from 1842 until the transfer of its sovereignty to the People's Republic of China in 1997. The Sino-British Joint Declaration and the Basic Law of Hong Kong stipulate that Hong Kong operate with a high degree of autonomy until at least 2047, fifty years after the transfer. Under the policy of "one country, two systems", the Central People's Government is responsible for the territory's defence and foreign affairs, while the Government of Hong Kong is responsible for its own legal system, police force, monetary system, customs policy, immigration policy, and delegates to international organisations and events.

Macau 澳門特別行政區
See separate listing under Macau
In 1976, Lisbon redefined Macau as a "Chinese territory under Portuguese administration," and granted it a large measure of administrative, financial and economic autonomy. Portugal and China agreed in 1979 to regard Macau as "a Chinese territory under (temporary) Portuguese administration". Negotiations between the Chinese and Portuguese governments on the question of Macau started in June 1986. In 1987, an international treaty, known as the Sino-Portuguese Joint Declaration, was signed to make Macau a special administrative region of China. The Chinese government assumed sovereignty over Macau on December 20, 1999.
