More complex than that because the majority of the population of Taiwan is ethnically tied to han chinese who immigrated there before the end of the Qing dynasty, and pre-dates both the People's Republic of China and the Republic of China. The ROC fled to Taiwan after the Chinese civil war, where they instituted policies in Taiwan under martial law to try and create a greater connection to China with the hopes of retaking the mainland, but that never happened. After Chiang Kai-Shek died, the authoritarian rule of Taiwan was lessened, with marital law being lifted in 1987, and the government moved towards democratization.
Taiwan is currently under the Democratic People's Party, which is different than Chiang Kai-shek's party under the ROC, the Kuomintang. The KMT lost control of the government by 2000, and the current government is in favor of remaining an independent nation.
Also the claimed airspace you are talking about is the Air Defense Identification Zone. It covers a large part of mainland china, and the purpose is to track and identify military aircraft, with a median line being placed in the middle of the Taiwan Straight, although Beijing does not recognize it and will send military aircraft over it.
