Why didn't the British showdown turn Jackie Chan into China?

Anyone who has seen movies and knows English knows that Jackie Chan plays a China man. Born in Guangxi, China, he lived in Ho Chi Minh City after the Vietnam War, then fled to Singapore and immigrated to Britain.

And in order to avoid the identity of China people, it is for the purpose of excessive trial, because it is cool to make trouble in other countries in the image of China people, but it is contrary to the national image (you know, civilization, harmony, honesty and friendliness).

There are many movies that change people from China to people from other countries, such as Red Dawn.
