The board for Eastern Europe is much more active and has many more people with experience going back from other countries. You might want to try it. Tthere you should find the answers to your questions.
It is my understanding, however, that it is up to each state to decide if they accept the degree from a specific school with quite a few states taking their cues from California. At this time I believe there are no English programs in China recognized by California. You would have to study in Chinese as of this time. This doesn't reflect on the quality of the program it's just that the program needs to make an official application which is quite comprehensive and time consuming.

Medical Board of California - International Medical Schools Disapproved by the State of California for a start.
What you are looking for is something like what the school Debrecen in
Hungary has where it says (English) meaning their English program is also accepted. After that check out some threads on the European board and contact the Medical Board of California yourself. They responded to me in about two days.
I doubt I can be of any more help but you can ask just in case.
