The U.S. side declared: The United States acknowledges that all Chinese on either side of the Taiwan Strait maintain there is but one China and that Taiwan is a part of China. The United States Government does not challenge that position.
这是英文原文!
其中写到,两岸中国人认为只有一个中国、台湾是中国一部分。
意思就是两岸中国人的想法,美国知道了,并且“does not challenge that position”。
