He was talking about China as a country and as an economy. If you come and visit, it is immediately obvious that there are problems.
By maintaining USD peg China has no independent monetary policy - it's monetary policy is directly influenced by Federal Reserve.
sure, but since 1994 they haven't really exercised that ultimate control:

and despite all promises to the contrary last year, they are still not exercising it to any substantial extent:
If they fail to maintain the peg, the RMB will most likely rise. Most US consumers are already exposed to the downside of this risk - they have expenses which will rise if the RMB goes up (e.g., all the goods they purchase which are made in China).
Holding RMB is a hedge against this.
I myself have a Long Straddle on CYB since some time last year, betting that it moves in either direction.
Let's just say hoping to make guaranteed profit cause chinese promised it isn't such a great strategy :)
They have 1 week more to move though, just in time for Paramount Leader's visit to D.C.
