China has started to sell US treasuries.

This is indeed an unusual move as it is the biggest selloff in nearly 2 and a half years.

However, this move might be misinterpreted by many because it could be that China was trying to stop its RMB from sliding further.

Like I said before, China is a consuming nation now and further slides in RMB will cause inflation in China to spike and slow down local consumption.  A rapid deterioration in RMB will impact imports and this will be bad for other export-oriented countries.
