Forget it. As long as China remains a dictatorship, investors will not pump in too much money - it's too uncertain what happens to your investment.
The reality is that everyone in China who managed to build up some wealth sooner or later exfiltrates it despite capital controls. And Russia prior to the war was similar. That's a large part of why London's and Vancouver's real estate markets got screwed up so hard - tons of real estate just sitting empty because it's just a proxy, a storage for wealth in a country that has laws and follows laws instead of the will of a dictator.
