However, political consensus and public opinion in Taiwan has evolved since 1992. There is significant difference between each faction's recognition for and understanding of the One China principle. The Pan-Blue Coalition parties, consisting of the Kuomintang, the People First Party, and the New Party, accept the One China principle. In particular, former President of the Republic of China, Ma Ying-jeou, stated in 2006 when he was the Kuomintang chairman that "One China is the Republic of China". Until the 1990s, the government actively stated that the ROC is the only legitimate "One China" while the PRC is illegitimate.
