One nation, two states

One nation, two states (simplified Chinese: 一国两府; traditional Chinese: 一國兩府; lit. 'one country, two governments') presuppose that China is "one country" (or "one nation") in cross-strait relations, but they want to recognize the political situation in which the government of the People's Republic of China (PRC) and the government of the Republic of China (ROC) coexist. This is mainly supported by some Kuomintang politicians who oppose the PRC's one country, two systems, and it was the U.S. government that first proposed it. The People's Republic of China opposes the One nation, two states because it claims to be China's "only legitimate government" (唯一合法政府). "One nation, two states" is basically based on one China principles, so it shouldn't be confused with "Two Chinas".
