Don't invite a poisonous snake into your house.
You might end up as lunch.

China is headed by a repressive, non-democratic, anti-free speech government.
They don't allow foreign companies unfettered access to their economy.
Partnerships with Chinese firms are demanded, they suck all the information from the foreign company and then dump the foreign partner.

Don't expect an independent judiciary in China, because they're controlled by the Chinese government. If your foreign company has a complaint and takes it to court, you will never win.
