Well, just because NewSoul is in China doesn't automatically make their company immune law suits. Did you hear about the case last year when Bandai sued the bootlegger "TT Hongli"? Here's a link to the old news:

Although, I haven't actively followed the developments of that suit (perhaps it's still going on?).
Konami is based in Japan by the way, not America. But, on the other hand, Hot Toys, who currently has the license for 1/6 MGS figures is located in China (just like NewSoul). So the possibility's there that we'll see some sort of legal thing coming out of this....
