The author neglected to point out that China has now seriously restricted money from leaving the Country. Without extra permission, seldom given right now, they are only allowed to take out 50,000 USD per year. As for the writers comments on new houses I know for a fact that many communities in the 905 belt make it very difficult for developers to get subdivisions built unless they are multiple or semi detached units.  Charging additional taxes to foreigners is also, in my opinion, discrimination and may not pass muster in a rights challenge.
