The only country you can apply for residency to without citizenship is the USA and if you want residency in the USA even though you said that you don't, you don't want to spend one year in China. It only hurts your application because US doctors don't trust a Chinese intern year.
I think you said you were from Ghana or something, if you can get residency back home that is good, but my main point is that doing a internship in China is a waste of time, maybe it'll help you in Ghana but at this time Chinese medicine is not very well recognized in the rest of the world.
Coming from a Caribbean school is already not a good sign, so the best thing for you to do is to get a US residency immediately and forget the Chinese internship which is in my opinion a obvious cash grab, otherwise most people will assume you did so poorly on the USMLE that you couldn't even get a US residency.
I doubt they will speak good english highly highly doubt it. Yes some doctors will be able to speak broken english but to interact with patients you must know Chinese and you must be able to speak it conversationally at least not to mention know a bit of medical chinese. This is another reason why people will not recognize a English speaker going to China for an internship, without fluent mandarin skills they know you won't have done much patient care.
I just read this on the website but it says its only for Faculty of Medicine students in China. This makes sense because the international students in China will know enough medical chinese by the end of their medical school to do the 1 year internship.
