China work visa should be applied in one's home country, but you can try to enquire about it from the Chinese embassy in Bangkok through the following ways:

Dear people,
as it happens NONE of phone numbers given to Chinese embassy in Thailand work in sense that all they do is go to an answering machine. There is no one to pick up a phone.

The same goes to email addresses. Last year and this year I have had two different questions and none of my emails has EVER been answered by Chinese embassy in Thailand.

Now, my question is important and is NOT answered anywhere in Chinese embassy homapages in Thailand:

1. Where can I get a health check up in Bangkok that is accepted as part of the Chinese work visa requirements.

If anyone knows the answer, it is highly appreciated.

The original medical certificate issued by a state-run medical organization will be ok.
