我們國也是寫 the status of Taiwan is treated as undetermined

The United States maintains that it recognises the People’s Republic of China (PRC) as the sole legal government of China, while simultaneously acknowledging — but not endorsing — the Chinese position that Taiwan is part of China. Under U.S. “One-China Policy,” the U.S. does not formally recognise Taiwan as an independent sovereign state, nor does it formally treat Taiwan as a province of the PRC. Rather, the U.S. declares that Taiwan’s final status is undetermined, and that any resolution of Taiwan’s future should come about by peaceful means, through dialogue, and with the consent of the people on both sides of the Taiwan Strait. The U.S. opposes any unilateral change to the status quo, whether by force or coercion. Meanwhile, although there are no formal diplomatic relations under international law, the U.S. continues to maintain robust unofficial relations with Taiwan — including commerce, cultural exchange, and provision of defensive assistance — under the framework of the Taiwan Relations Act (TRA) and related policy assurances.
