I would agree with what you said in regard to a medical. If it is not in the contract you should not have to take one. If it is not in the contract it is optional for an FT, not compulsory!

Anyway, who do the Chinese think they are, expecting foreigners to take medical examinations! I will do a medical in my own country if needed, not in some Chinese medical centre with arrogant, rude, racist, and incompetent "doctors"!
