하나의 중국
The "One-China policy" is a policy asserting that there is only one sovereign state under the name China, as opposed to the idea that there are two states, the People's Republic of China (PRC) and the Republic of China (ROC), whose official names incorporate "China". Many states follow a one-China policy, but the meanings are not the same. It also differs from "One China Principle", the term used by PRC.
