It is a Chinese government requirement that any company doing business in China MUST have its R&D located there.
I heard at one time that any business that wanted to manufacture there had to turn over all business models and all connected patent information.
If that’s true, think about the transfers of technical information and know how. There’s a lot of strategic things involved.
I’ve been saying for 25 years now, that we have gifted the Chinese with 5-7 decades of technical information.
That’s the dumbest thing I’ve ever seen.
