evidence: Before it became a special administrative region of China in 1999, Macau followed the colonial constitution promulgated in 1976; it was administered by a governor, who in agreement with the Legislative Assembly was appointed by the Portuguese president. With the transfer of sovereignty over the territory to China, the Basic Law of the Macau Special Administrative Region, which outlined a policy of "one country, two systems," went into effect. For a period of 50 years, Macau will thus retain its capitalist economy and some political autonomy, but foreign policy and defense matters will remain under Chinese administration.
