Doesn't matter. China is way overextended, and really they have only a beginner's idea of how the world works and what they've done to themselves.
It doesn't even matter if they see hard times or not, because when it comes to currencies in times like these, stability is all that matters. So, at the slightest tremor, it'll be back to the dollar, and the USA.
The dollar (the US) is like original formula Coca Cola: what you have when you don't really trust the rest. And no one really trusts China: everyone remembers, well, everyone except that strident fool Jimmy Rogers, that China is still a communist dictatorship, at bottom.
