It sure can happen, but u have to remember that the US legislated the deal asa security threat since it dealt with Cargo.

U cant do the same with Real Estate unless its a government estate.
Even then there are exceptions which i am personally aware of (Germany to be specific).

When it comes to china, its a FX issue and the trade benefit which it has with the rest of the world.

Sub-prime is in no way temporary
Do u call a Loan drawdown for a real estate projected in the profits of a financial institution for the next 20 years temporary

I dont think so!
