De facto it is. But according to the one China policy that the US subscribes to, it's not. It's also not a part of many UN organisations.

Well tell that to your government. They are not saying that. And until most of the UN agrees with that, Taiwan can't be considered a country.

In fact, as a Taiwanese person, I'd prefer it if people like yourself didn't just say platitudes like Taiwan is a country and then do literally nothing in your votes to make that happen. You disappoint me.
