That is just a simplistic caricature of what actually happens. Any company has to first accept the tax breaks and business incentives (land resources, loans, no red-tape, easier access to market etc) that the Chinese government employs to attract foreign businesses in specific markets. China has structured those incentives to benefit them - which include setting up a joint venture with a Chinese company. If the company is a state owned enterprise, your benefits might increase even further. You have to obviously transfer the IP for the factory to actually make the thing you want. China, with its communist past has their own understanding of property rights. I believe even its citizens cannot own land - everything belongs to the government. I'm not an IP law expert, so I don't know what international laws China is or isn't violating, but I don't expect China to respect US laws, without a treaty.
