China Business Visa for New Zealander

Hey,

I have been in China for the last two months on a business F (got a 30 day business F, and then extended it once for an additional 30 days). I am travelling to Bangkok this weekend where I hope to get a new business F for at least 60 days back into PRC. Is this possible to do in Bangkok? I know I can definitely go back to New Zealand to get it done, but I can not afford the flights, so trying to do it the easiest way.

Any advice would be hugely appreciated!! :) Thank you!
