Pro-independence supporters point out 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. Hence, the conditions of Article 10 of the Sino-Japanese Peace Treaty in regard to "in accordance with the laws and regulations which have been or may hereafter be enforced by the Republic of China in Taiwan..." was argued to have yet to be fulfilled.
