Is the Chinese Government a Buyer of Last Resort?

One fourth to one fifth of all f china's housing stock is empty. There's nobody living in it. That'sanat's an example of a bubble in really badly and inefficiently allocated capital. We want to get away from this investment in real estate. The chinese government technically owns everything. Does the chinese government take it back? If there are properties out there that don't have any buyers, do they buy them as last resort?
