Agreed. Yuan is too closely regulated to stay in China. I doubt it would be viable unless China first steps up their _attitude_ towards being a currency provider. The EMU is an amalgamation of countries that barely hold together, have vastly different opinions on government spending, and isn't already a "world currency." I do think we'll eventually have a single currency on the planet, but the question is what happens in my lifetime. And that's much less certain.
