Actually as an American you can simply go to China on a, "whatever" visa and start working on arrival, there is no enforcement of the law except if you start making real money and stepping in someone's toes. It's virtually impossible for average Chinese to get to the US even as a tourist. Western Tech companies doing well? 3M, Microsoft, Yahoo,...it depends on how good of a job they did forming relationships or paying bribes and how immune their business model is to asset siezure and copying.
