Hong Kong was built by the Chinese people, Europeans conquered many lands around the world, many former colonies are very poor like India. besides, China used 40 years to build Shenzhen from nothing, now Shenzhen's GDP is bigger than Hong kong and in frastructure, Hong kong looks like a shithole comparing to Shenzhen.Europeans also built hong kong into a financial centre, but you chinese would cry if the europeans took ownership of it again. Because lets be honest european hong kong is better in pretty much all ways then chinese owned hong kong.
So using your logic it should be ok for europeans to own china since you know they will make it better then it was in terms of buildings and what not.
