Sure, there are similarities between many groups of people in terms of appearance, culture, language, etc. However, here are some interesting facts about Taiwan:

Taiwan has its own language, Taiwanese, that is slowly being pushed out by Chinese. Additionally, Taiwanese people who read and write Chinese use traditional Chinese characters rather than the simplified Chinese characters (introduced by the Communists).

Taiwan is the global leader in manufacturing computer chips because their manufacturing processes are years ahead of anyone else (for more info, look up TSMC).

Taiwan is a very modern democracy and they deserve to be recognized as an independent country.
