Awgee, here is a prediction on China. Within one week, another senior official will make a statement that counters what was said last night. There are a couple of reasons I believe this to be true. One cultural, and the other financial.
On the cultural side, it has been my observation that Chinese people frequently say things that are deeply offensive to Westerners. Whether it is related to culture, translation, or English as a second language, you see it quite often. This isn't the first time that some Chinese official has spoken of pulling out of dollar denominated investments. Every time something similar has happened in the past, another announcement has followed in days from a higher ranking official that offsets the initial announcements. Similarly, occasionally you will read of some ranking member of the Chinese military making statements about nuclear weapons or ICBMs and the impact they can have on various regions in the US. Within days, there will always be an announcement that overrides the initial announcement and attempts to perform damage control. On a more personal level, I am a computer geek and am involved in design of computerized components of major weapons systems. One member of my team is a brilliant scientist who immigrated from China about 15 years ago. While he is technically very astute, I find myself always having to jump in and perform damage control when he sends out messages that ruffle the feathers of everyone around us.
On the financial/technical side, I am sure that you have heard Fleckenstein question who will stop in front of the freight train if China ever did decide that dollar divestiture is in their best interest.
Basically we have an arrangement with the Chinese. We give them toxic paper in return for their toxic toys. It's essentially a Prisoner's Dilemma. Both sides benefit if no one makes a move. And though there is a theoretical "first movers" advantage for one side to break status quo, the size of the problem is such that China would do themselves irreparable harm if they tried to distance themselves from the dollar.
While I still believe that the direction of the dollar is down (who could argue with Giselle?), I think that it will be more orderly than others believe. I also recognize that the forces of capitalism are such that dollar depreciation will set the stage for future dollar demand as the price of goods and services produced in the US become more competitive and we stop exporting dollars for toxic toys.
