One China was the formulation held by the ROC government before the 1990s, but it was asserted that the one China was the Republic of China rather than PRC. However, in 1991, President Lee Teng-hui indicated that he would not challenge the Communist authorities to rule mainland China. This is a significant point in the history of Cross-Strait relations in that a president of the ROC no longer claims administrative authority over mainland China. Henceforth, the Taiwan independence movement gained a political boost, and under Lee's administration the issue is no longer who rules mainland China, but who claims legitimacy over Taiwan and the surrounding islands. Over the course of the 1990s, President Lee appeared to drift away from the One-China formulation, leading many to believe that he was actually sympathetic to Taiwan independence. In 1999, Lee proposed a special state-to-state relations for mainland China–Taiwan relations which was received angrily by Beijing, which ended semi-official dialogue until June 2008, when ARATS and SEF met, and in which President Ma Ying-jeou reiterated the 1992 Consensus and the different interpretation on "One China".
