I believe this hand basket is about to be unearthed for an autopsy unless it's ghost stops spooking fears into the US .

Sooner or later China will have to unveil it's content maybe sometimes next year , when they have a better view of the debt crisis in europe , in a second phase of the yuan's reevaluation . China likes the step by step progress as it dictates the pace of evolution and since they're in control of the agenda , they will use the timing in their own interest .

It's also in China's interest to establish the yuan as a reserve currency over the next decade in order to stabilise it's economy without having to export it's wealth into the US treasury and depend on US decision to protect that wealth .

The expension of the US debt must be very scary to them as they watch helpless , the US government making record deficits .

They would probably rather improve their own health care system or social net with some of that money instead of seeing the american public taking advantage of the money they put in US bonds to do the same .
