evidence: At the adoption of Additional Articles of the Constitution of the Republic of China in the 1990s, these islands collectively form the "Free area of the Republic of China" or known alternatively as "Taiwan Area", which legally defines the territorial extent under the actual control of the ROC government. [...] Matsu Islands [edit]- Matsu Islands (馬祖列島) [...] The PRC claims the islands of Taiwan and Penghu as part of its 23rd Taiwan Province, together with the Japanese-controlled Senkaku Islands (claimed as "Diaoyudao Islands"), which are also claimed by the ROC as part of its own Taiwan Province. The PRC claims Kinmen (Quemoy) as a county of the prefecture-level city Quanzhou, in Fujian Province. Matsu is claimed as part of Lianjiang County, part of Fuzhou, in Fujian Province. The Wuqiu islands are claimed as part of Xiuyu District, a district of the prefecture-level city Putian, in Fujian Province. Pratas Island is claimed as part of Chengqu in Shanwei (Swabue) Guangdong Province. The Nansha Islands controlled by the ROC, i.e. Taiping Island and Zhongzhou Reef, are claimed as part of Sansha, in Hainan Province. The PRC thus claims the ROC-controlled islands as part of its own Taiwan Province (Taiwan and Penghu), Fujian Province (Kinmen, Matsu and Wuqiu), Guangdong Province (Dongsha) and Hainan Province (Nansha).
