evidence: - Article 4 of the ROC Constitution clearly states that "The territory of the Republic of China" is defined "according to its existing national boundaries..." Taiwan was historically part of China and is, therefore, naturally included therein. Also, as Treaty of Shimonoseki is void ab initio, China has never legally dispossessed of the sovereignty of the territory. There is, accordingly, no need to have a National Assembly resolution to include the territory. [...] - In the Joint Communique of the Government of Japan and the Government of the People's Republic of China to the end of the Treaty of Taipei, the document signifying the commencement of the PRC and Japan's formal relations, Japan in article 3 stated that it fully understands and respects the position of the Government of the People's Republic of China that Taiwan is an inalienable part of the territory of the People's Republic of China. Japan also firmly maintains its stand under Article 8 of the Potsdam Declaration, which says, "the terms of the Cairo Declaration shall be carried out". The Cairo Declaration says, "All territories Japan has stolen from China, including Manchuria, Taiwan, and the Pescadores, shall be restored to the Republic of China". The PRC argues that it is a successor state of the ROC and is therefore entitled to all of the ROC's holdings and benefits.[120]
