evidence: Macau, special administrative region (Pinyin: tebie xingzhengqu; Wade-Giles romanization: t’e-pieh hsing-cheng-ch’ü) of China, on the country’s southern coast. Macau is located on the southwestern corner of the Pearl (Zhu) River (Chu Chiang) estuary (at the head of which is the port of Guangzhou [Canton]) and stands opposite the Hong Kong Special Administrative Region, which is some 40 miles (60 km) away on the eastern side of the estuary. [...] 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.
