What to do when your Chinese ex-wife runs away with your child?

I’ve just received a rather disturbing e-mail from a fellow expat here in China. As I really don’t have any experience, or know anything about the laws or official steps that can be taken, I figured I’d post it on here in hopes that our wonderful readers might have some advice to give.

The e-mail reads:

Hello. I wonder if you could help me. I am an American in China and my Chinese ex-wife and her boyfriend have abducted my five year old daughter. I need some legal help to try to get my daughter back. I’m alone and I don’t know what to do and could sure use some help and support.

Thank you

Jon’s asking, anyone have any ideas what can be done?
