Treaty of Taipei
Significantly, as the ROC officially announced the total abrogation of the Treaty of Shimonoseki on more than one occasion, supporters of the ROC would 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.
