Technically, the situation is similar to the two Koreas, it's two Chinas at war, at least the mainland has never given up of uniting China, or conquering Taiwan. Since the 60s though, after realizing military action against Taiwan was too risky due to US protection, the issue has been left alone. But some voices have raised since the 90s to unite Taiwan through political/economic means, like Hong Kong and Macau. Uniting Taiwan is a national pride issue for a lot of Chinese people, so there is political capital to be gained. On the Taiwan side, it is a rich country, and people in general prefer their current lives, thus see no reason to be "united". There are some business people/politicians who benefit from closer ties with mainland, but they are the minority.
