in 1949 it reneged on its agreement in order to preserve its claim over mainland China. The Additional Articles of the 1990s did not alter national boundaries, but suspended articles regarding Mongolian and Tibetan representatives. The ROC began to accept the Mongolian passport and removed clauses referring to Outer Mongolia from the Act Governing Relations between the People of the Taiwan Area and the Mainland Area in 2002. In 2012 the Mainland Affairs Council issued a statement clarifying that Outer Mongolia was not part of the ROC's national territory in 1947, and that the termination of the Sino-Soviet Treaty had not altered national territory according to the Constitution. The Mongolian and Tibetan Affairs Commission in the Executive Yuan was abolished in 2017. Major camps Taiwan's political scene is divided into two major camps in terms of cross-Strait relations, i.e. how Taiwan should relate to China or the PRC. The Pan-Green Coalition (e.g. the Democratic Progressive Party) leans pro-independence, and the Pan-Blue Coalition (e.g. the Kuomintang) leans pro-unification. Moderates in both camps regard the Republic of China as a sovereign independent state, but .

It called also for general use of "Taiwan" as the country's name, without abolishing its formal name, the "Republic of China". The name "Taiwan" has been used increasingly often after the emergence of the Taiwanese independence movement. Some members of the coalition, such as former President Chen Shui-bian, argue that it is unnecessary to proclaim independence because "Taiwan is already an independent, sovereign country" and the Republic of China is the same as Taiwan. Despite being a member of KMT prior to and during his presidency, Lee Teng-hui also held a similar view and was a supporter of the Taiwanization movement. TSP and GPT have adopted a line that aggressive route more than the DPP, in order to win over pro-independence voters who are dissatisfied with the DPP's conservative stance.
