“Back in the early stages of the financial crisis, wags joked that our trade with China had turned out to be fair and balanced after all: They sold us poison toys and tainted seafood; we sold them fraudulent securities.

But these days, both sides of that deal are breaking down. On one side, the world’s appetite for Chinese goods has fallen off sharply. China’s exports have plunged in recent months and are now down 26 percent from a year ago. On the other side, the Chinese are evidently getting anxious about those securities.

But China still seems to have unrealistic expectations. And that’s a problem for all of us.”
