Fascinating little story that somehow brings to mind places like Kings Garden Villa in Beijing, and much of the city of Ordos.
I would wager that at least some of the money that has found its way to Manhattan is coming from Chinese investors who would rather wait for tenants who can afford their desired rents than rent out at less and undermine the likely ridiculous sums they paid for the properties.
This is not a uniquely Chinese behavior, but it is a practice that is notably common among property owners in China. What is more, the sources of cash flowing out of China and into North American investment properties are certainly not limited to giant, high-profile developers like Wanda. So while it would assume far too much that Chinese money is the cause of High Rent Blight in New York, it is likely a contributing factor.
