No need to do anything but wait. All fiat currencies have followed the same path. Although the FRN has had a pretty good run, perhaps the longest in the history of fiat currencies, it looks like the game is almost up.
The Chinese president also said that U.S. Federal Reserve policy was fueling inflation in emerging economies.
That's actually a fair accusation, but it's almost as true for the Yuan. The Chinese government has been understating their inflation rate for a number of years now. Perhaps the past decade. They aren't as careful at it as the Federal Reserve, and they are going to have a currency crisis pretty soon. An in China, that is likely to lead to civil unrest, since the working man there ddoesn't even have the pretense of having some say in his own government's policies, and therefore the only path towards reform is bloody. I would caution anyone considering large investments into China. We know that China is a powder keg and the fuse is already lit, we just don't know how long the fuse is.
