Apparently these rich Chinese are not aware of rich Americans fleeing the USA (going Galt).
China is the crony-capitalist center of the world. You do not get rich there without sucking-up to, bribing, cajoling the omnipresent government and its officials.
Smart people know that it can change at any time - for the wealthy, their property rights are not secure.
(BTW - I see the same thing developing in the USA)
Funny how with the exception of Japan, most of those destinations are within the anglosphere. I’d guess that most of those heading to the all-encompassing term ‘Europe’ are in fact heading for Britain...
