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.

>Taiwan is already independent.

That is a very controversial statement, and one that both Taipei and Beijing disagree with.

I suppose, though that's not really how I tend to see it phrased on socials or in the media.

Before Trump set his sights on Greenland, Denmark also considered Kosovo to be independent.
