One interpretation of one China is that only one geographical region of China exists, which was split between two Chinese governments during the Chinese Civil War. This is largely the position of current supporters of Chinese reunification in Mainland China, who believe that "one China" should eventually reunite under a single government. Starting in 2005, this position has become close enough to the position of the PRC, allowing high-level dialogue between the Communist Party of China and the Pan-Blue Coalition of the ROC.
