The One China concept is different from the "One China principle", which is the principle that insists both Taiwan and mainland China are inalienable parts of a single "China". A modified form of the "One China" principle known as the "1992 Consensus" is the current policy of the PRC government. Under this "consensus", both governments "agree" that there is only one sovereign state encompassing both mainland China and Taiwan, but disagree about which of the two governments is the legitimate government of this state.
