It's understandable though from China's perspective, that they aren't willing to give up important strategic sectors like social media or internet search to some US corporation. Especially so with their intention of being a rivaling global superpower to US one day. But it seems the economical aspect of increasing the revenues of Chinese companies has been as important or even more, which makes this practise more or less just cheating. Not that others are playing always fair, but China seems to be doing it considerably more than the others.
Just as an anecdote, AWS offers its Chinese region as a separately owned Chinese company, completely separate from other AWS regions. To me it speaks volumes how restrictive and hostile the Chinese market is to foreign companies, can you imagine having to do the same for each country? It would be a nightmare for global economy. https://techcrunch.com/2017/11/13/aws-exits-china/
