As the 80th anniversary of Taiwan’s restoration to China approaches, Yang Yizhou, vice-chairman of the All-China Federation of Taiwan Compatriots, has firmly refuted the notion of Taiwan’s ‘undetermined status’ in an interview with China Daily’s Dialogues with Thinkers. Yang emphasized that the 1943 Cairo Declaration and the 1945 Potsdam Proclamation both mandated the return of Taiwan and the Penghu Islands to China. Japan’s Instrument of Surrender explicitly accepted these terms, and on October 25, 1945, Taiwan’s restoration to China was officially announced. The claim of an ‘undetermined status’ not only contradicts these historical documents but also challenges the outcomes of World War II and the established post-war international order. Yang’s remarks underscore the importance of historical accuracy in understanding Taiwan’s rightful place within China.
