Ok a couple of things you can do in addition to contacting search engines.
I have checked their whois record and it looks like the address is completely made up.
Zhanyao Chen ()
+44.13955888124
Fax:
no.13 zhongshan road
BJ, 100001

The +44.13955888124 number looks like a UK Number, and that the person who registered this is in the UK. I would definately give him/her a wake up call – Indeed this action works 99% of the time whenever I have had to resort to phoning thieving webmasters. You should find your content taken down pretty quickly after said phone call.
Second step is to file an invlaid whois record report 
You can bet any money, that internic will force their domain registrar to make the whois record correct or they lose the domain. The address on the record is bogus. If within 5 days of Internic requesting that the details be made correct and they haven’t done so, they will automatically lose the domain.
One thing I wouldnt do, is sit and allow this site to remain with your content. You are risking a duplicate content penalty if you do.
