The Basic Law of the Macao Special Administrative Region of the People's Republic of China (Chinese: 中華人民共和國澳門特別行政區基本法, Portuguese: Lei Básica da Região Administrativa Especial de Macau da República Popular da China) is the constitutional document of Macau, replacing the Estatuto Orgânico de Macau. It was adopted on 31 March 1993 by China's National People's Congress and promulgated by President Jiang Zemin; it came into effect on 20 December 1999, following the transfer of sovereignty over Macau from Portugal to China.
In accordance with Article 31 of the Constitution of the People's Republic of China, Macau has special administrative region status, which provides constitutional guarantees for implementing the policy of "one country, two systems" and the constitutional basis for enacting the Basic Law of the Macau Special Administrative Region. The Macau Special Administrative Region is directly under the authority of the central government of China in Beijing, which controls the foreign policy and defense of Macau but otherwise grants the region a "high degree of autonomy."
