When are Western companies going to realize what's going on? I'm Asian. Asia has very little respect for intellectual property law. They predominantly believe that if you want to protect IP, you need to secure it yourself. And there's an unwritten rule that everyone is going to try to steal your IP, so you damn well better secure it instead of relying on some IP law. It's accepted enough that you can be fired if your employer orders you to spy on a competitor and you refuse.
China's MO is to require you to share technology and/or build your factories in China in order to "get access" to the market. The promise is that after you do this, you will be able to sell your products in China. The reality is that they will steal your IP and manufacturing technologies, build their own competing factory which underbids you, and effectively shut you out of their market again, only now they have all your technology without having to have invested decades of R&D to develop it on their own.

The Chinese are probably astounded that Western companies are falling for this, and keep falling for it. Why waste time hunting for deer when the sheep willingly line up to be slaughtered?
