No, China is. They’ve been hoodwinked into buying worthless American toxic debt. Simultaneously, the Chinese are trying to manage a hyper-inflated, speculative housing market of leviathan proportions! Just wait when THEIR housing bubble bursts! Billions of people–whose personal wealth disappears overnight–will hit the streets in rage and desperation. You can’t give the masses a taste of honey, and then replace it with vinegar. The massive Chinese middle-class (and its taste for the good life) is a force to be reckoned with!

“Although China is the largest owner of US Treasury bonds, the US is still the worlds largest economy, and we are paying close attention to the growth of the US economy” says Premier Wen Jia-Bao. “We have faith that the economic measures put in place by the government of President Obama will come to fruition. As we have given the US large sums of money, it is natural that we worry about the security of our assets. I myself am worried. But I also think that by ensuring the US maintains trust, and honours their promises, they can guarantee the stability of China’s assets.”
