My comment: I assumed AIT發言人 used Chinese. But it is still unclear whether it is spoken or written (by AIT發言人).
(b) AIT's written statement in English issued on Sept 15, 2025:
" 'China intentionally mischaracterises World War Two-era documents, including the Cairo Declaration, the Potsdam Proclamation, and the Treaty of San Francisco, to try to support its coercive campaign to subjugate Taiwan,' the American Institute in Taiwan said in an statement on Monday [Sept 15].
" 'Beijing's narratives are simply false, and none of these documents determined Taiwan's ultimate political status,' the de facto US embassy added in the statement emailed to Reuters.
