That is one dangerous game they are playing, given the scale and significance of the dollar. The consequences could (and will be IMO) dire.
We obviously approach this from differing angles. My contention is that much of this is engineered, rather than the bungling errors of economic halfwits, which I suspect is how you approach this.
There are no more economic levers to pull, they can't afford to effect substantive stimulus, they cannot reduce interest rates. A dose of high inflation might be what their economy needs.
What action could they take to prevent the collapse?
Buy them Yankee dollars.
Remember the Chinese need markets and the US represents the largest richest market around.
