As someone who used to work in country list related things, the existence of Taiwan as a country flag codepoint at all would be an issue for China. China will complain if you include Taiwan, and Taiwan will complain if omitted, so it's not fun appeasing both sides.
Agreed, just pointing it out. In our system, we had to display 'Taiwan, Province of China' for the Chinese users, and 'Taiwan' to everyone else, though that was just UI and the backend treated it identically.
