Taiwan is already independent. Surely the normal way to refer to it would be as coming out against assimilation with mainland China?
The official position of Taiwan (Republic of China) and the People's Republic of China is that they're rival governments of the same China.
The Taiwanese government has never formally declared itself independent from the mainland. Such a declaration would likely cause the PRC to invade.
This is a glaring admission ChatGPT is a poor man's Claude in the literal sense.
