Hypothetical scenario: US Treasuries go south, the bubble bursts. The next day Chinese announce they start selling their Treasuries on the open market. So instead of keeping your money with the most indebted Government on the face of the planet, you keep it with the biggest creditor in the world. Doesn't sound as a bad deal, huh? And as an extra bonus just to make sure everyone drops US Treasuries ASAP to buy the Chinese paper: tie the currency to gold. Guarantee that yuan is as good as gold. Why not? Yuan reserve currency of the world, so the same mistakes can be made all over again ;-)
This what Keynsians call in this case problem for Chinese I call a huge win. Keynsians will tell you: oh, but now Chinese exports will get prohibitively expensive! And I say: BS! The yuan currency will go up in value up to 6 times. Why to export anywhere when you just got 1 billion new consumers worth 6 times more than before?! Next step: rest of the world starts producing again, including US. China stops being factory of the world as we can't afford their stuff anymore. We need to relearn how to build and assemble it again. Voila, here you have balance back in the system.
