I don't know the difference between Chinese cuisine and Taiwanese one.
In Japan, there seems to be no difference between them. I've heard some Taiwanese restaurants in Japan avoid naming "Chinese restaurant" due to bad impression against China.
Furthermore, Some Cantonese restaurants serve foods which are the same ones as Chinese foods.
