The Chinkernese cannot own property in China since the CCP owns it all.
So they come here to purchase property. They bought the Waldorf-Astoria Hotel several years ago and are planning to turn the top 20 floors into condos. (They are also buying up farm land.)
Lots of luck with that now seeing as NYC tax policies have driven the wealthy to tax friendly places such as Florida and Texas. ;)
