the Republic of China shall be deemed to include all the inhabitants and former inhabitants of Taiwan (Formosa) and Penghu (the Pescadores) and their descendants who are of the Chinese nationality in accordance with the laws and regulations which have been or may hereafter be enforced by the Republic of China in Taiwan (Formosa) and Penghu (the Pescadores)." Ng Chiautong, chairman of the organization World United Formosans for Independence (WUFI), argued that Article 10 is not an affirmative definition of the Chinese nationality of the Taiwanese people but merely an agreement for the sake of convenience on the treatment of the Taiwanese as ROC nationals, because otherwise the inhabitants of Taiwan who were formerly Japanese nationals would not be able to travel to Japan. He also argues that the Treaty of Taipei does not call the Taiwanese "Chinese nationals" but prefers the term "residents". Independence supporters claim that the Nationality Law of the Republic of China was originally promulgated in February 1929, when Taiwan was argued to be a de jure part of Japan. The Nationality Law was revised in February 2000; however, there were no articles addressing the mass naturalization of Taiwanese persons as ROC citizens. They also point out that neither the San Francisco Treaty nor the Treaty of Taipei specifically provide for a transfer of sovereignty of Taiwan from Japan to China. Both have provisions for the renunciation of Japan's claims of sovereignty, yet neither provides for a mechanism of transfer to China. As the ROC officially announced the abrogation of the Treaty of Shimonoseki on more than one occasion, supporters of the ROC argue that China's sovereignty over Taiwan was never in dispute. Moreover, Japan and the ROC by the Treaty of Taipei further "recognised that all treaties, conventions and agreements concluded before December 9, 1941, between Japan and China have become null and void as a consequence of the war". It was therefore argued that the ROC Nationality Law which was promulgated in February 1929 would have applied to the residents on Taiwan, and it was unnecessary to address any nationality issues in the February 2000 revision. On the other hand, Lung-chu Chen and W. M. Reisman, writing in the Yale Law Journal in 1972, argued that the title to Taiwan territory vested in Japan at the time of, and/or because of, the Treaty of Shimonoseki, as the language of the Treaty clearly indicated.
