An incredible statement - made even more so by possibly being true.
It was less than ten years ago that Hong Kong might have been considered the leading city in all of China and certainly the most dynamic on the axes that he is considering.
FWIW, I think the CCP has made a tactical error in their handling of Hong Kong:
As a business owner in Hong Kong I was, previously, only peripherally and philosophically concerned with the behavior of the party throughout the rest of the country - it was possible to compartmentalize the "two systems".
But if Hong Kong is just another Chinese city and if there is only one "system" then I am forced to very critically reconsider my business activities there - small as they are.
This makes me very sad - Hong Kong has for my entire adult life been my favorite city and the city I thought was the most interesting and exciting.
