The Taiwan Area, also called the Taiwan Area of the Republic of China, the free area of the Republic of China, and the "Tai-Min Area (Taiwan and Fuchien)", is a term used to refer to the territories under the effective control of the Republic of China (ROC, commonly known as "Taiwan"). It has been in official use since the Additional Articles of the Constitution of the Republic of China took effect, ending temporary anti-communist provisions on 1 May 1991. The term is also used in the 1992 Cross-Strait Act.
The area currently under the definition consists of the island groups of Taiwan, Penghu, Kinmen, Matsu and some minor islands. The collective term "Tai-Peng-Kin-Ma" is literally equivalent except that it only refers to the geographical areas of Taiwan, Penghu, Kinmen and Matsu Area, to the exclusion of Wuqiu, Dongsha Island, and Taiping Island.
