Here's what the May 2007 World Bank update has to say about Chinese economic
performance: Growth prospects are good; GDP is expected to rise by 10.4 percent
this year; the stock market is booming, export growth is surging, the trade

Krugman asks if such a scenario is possible with foreign purchases of US
assets which sustain a continuation of the US trade deficit.

that the increasing share of US securities in foreign hands is unsustainable?
They could start to unload their holdings of dollar-denominated assets,
precipitously driving down the dollar exchange rate.
