You don't say whether or not you are a US citizen, but, especially if you were, this is what one could do.
Telephone the US Embaassy, or go there.
Find out the the name of the doctor they use in Beijing for their staff. With that as a starting point you might get referred further to the man you want.
You might also see if you could get through to the Air Attache. Probably have to leave a letter of explanation for someone of his rank.
You could also repeat your post, perhaps worded slightly differently in the South Asia and Far East Forum?
Best of luck.
