Regardless of your opinion on Chinese politics (or your opinion on California politics for that matter), Shenzhen is absolutely blowing up. Just talking with random tech and startup people there, you feel an energy and optimism that is hard to find in the bay area these days. As a non-Chinese citizen, investing in property there feels a bit too risky for my appetite, but I certainly would not bet against it.
Unlike other places, people don't own land in China right? You can only lease it for x number of years. That changes the dynamics of the real estate market.
