This is nothing new. It's been that way for a number of years. The foreign power owning the most in the US is the only thing that changes.

A glimpse of what might happen occurred several months ago. I believe it was a Japanese company that needed some quick cash. They dumped the securities they owned here. It caused a hugh drop in the market for the day. The market did rebound the next day when the company made an official announcement that their sell-off was a one time occurence.
