I've got a popular dating/connections website here in the U.S. I recently found a Chinese site (on a .cn domain) that offers the same service in China - but they've completely ripped off the look and feel of my site - same fonts, same layout, same design, same navigation - everything!
Now, obviously we're in different markets, so we're not competing with each other (yet) but I don't like this. I know what I can do in the U.S., but what are my options when dealing with a Chinese company and domain?
