I don't want to get involved in politics. But I have to point out "Taiwan is literally the Republic of China." is 100% correct. The official name of Taiwan is Republic of China (ROC). On the cover of Taiwan passport, you can only see Republic of China. The interesting thing is the claimed territory of Republic of China includes the China mainland and Mongolia, not just Taiwan island. The official name of China mainland is People's Republic of China (PRC), literally same to Republic of China (ROC). It's too complex for western people to understand. Just refer them as China and Taiwan.

I am from China mainland, having friends and colleagues from Taiwan. Don't want to see wars happen between PRC and ROC.
