> According to the U.S.’s own policy, Taiwan and what we call China are the same country.
That's a mistaken interpretation and it has been clarified on numerous occasions.
There are two critical words to the context: recognize and acknowledge. And two separate entities to be considered as far as the US is concerned: China and Taiwan. The US has intentionally left the situation in limbo, to neither give in to China nor prompt a military confrontation between China and Taiwan.
The US does not officially recognize China and Taiwan as one. The US "acknowledges" China's position; specifically China's belief that they are one country.
Here is a good explanation:
> The United States did not, however, give in to Chinese demands that it recognize Chinese sovereignty over Taiwan (which is the name preferred by the United States since it opted to de-recognize the ROC). Instead, Washington acknowledged the Chinese position that Taiwan was part of China. For geopolitical reasons, both the United States and the PRC were willing to go forward with diplomatic recognition despite their differences on this matter. When China attempted to change the Chinese text from the original acknowledge to recognize, Deputy Secretary of State Warren Christopher told a Senate hearing questioner, “[W]e regard the English text as being the binding text. We regard the word ‘acknowledge’ as being the word that is determinative for the U.S.” In the August 17, 1982, U.S.-China Communique, the United States went one step further, stating that it had no intention of pursuing a policy of “two Chinas” or “one China, one Taiwan.”
> To this day, the U.S. “one China” position stands: the United States recognizes the PRC as the sole legal government of China but only acknowledges the Chinese position that Taiwan is part of China.
