China has a patent system. I don't know about copyright, but that's less significant for tech progress (and trademarks not at all).

I would guess foreign owned patents would not fare well, because it's not in China's interest (USA did the same thing some time ago), but that reasoning doesn't apply to domestically owned patents.

Apparently, in 2014 patent owners won about 80% of their cases BUT the damages granted are "maddeningly" low. The article isn't clear if that's also true for domestically owned patents. http://maxhamfirm.com/patent-litigation-china/

One mechanism is that it's harder to prove damages under Chinese Law, though people say it's changing. Though none of the cases are about real technological progress, more design/trademark like designs (I guess it's the same in the west though too) https://www.limegreenipnews.com/2018/03/calculating-larger-p...
