People who live in Taiwan are ethnically Chinese and speak Chinese and consider themselves Chinese, and the Taiwanese government considers itself the legitimate government of China (or at least used to until fairly recently). I would say that it is fair to call them Chinese, even if they are not part of the PRC. Still doesn’t really excuse the article calling it ‘a nation’ when referring to both of them.
