The US and Canada have the same problem: too much absentee (read, foreign) ownership of real property. The answer is staring people right in the face. Canada usually runs a trade deficit, and it is a pretty good place to "launder" USD via the real estate channel. If US and Canadian trading partners don't want to own US or Candian paper, they can buy real estate or sports teams or corporations in those countries. That simply should not be allowed. If they want to buy our outputs with our money, fine. If they want to hold our debt while they think about what outputs to buy, fine. But they can't own our land or our capital plant. That seems so obvious, especially because North Americans trying to do business in China face precisely that sort of restriction.
What am I missing?
