Whereas my Alien Registration Card in Korea, aka my ID in Korea, presents something a bit confusing.
Situation in Sweden is the same as Korea. As they do not offer anything like ID, this was what I had back then, a statement of my Personal Number. They identify Taiwan ROC as Republiken Kina (Taiwan). Kina is China in Swedish.
I do not have my Hong Kong ID with me now, however, nationality is not stated on the ID anyway(THUMBS UP HONG KONG!).
