But there’s a growing group of market professionals who see a different picture altogether. These self-styled China bears take the less popular view: that the much-vaunted Chinese economic miracle is nothing but a paper dragon. In fact, they argue that the Chinese have dangerously overheated their economy, building malls, luxury stores and infrastructure for which there is almost no demand, and that the entire system is teetering toward collapse.

A Chinese collapse, of course, would have profound effects on the United States, limiting China’s ability to buy U.S. debt and provoking unknown political changes inside the Chinese regime.

The China bears could be dismissed as a bunch of cranks and grumps except for one member of the group: hedge fund investor Jim Chanos…

Chanos and the other bears point to several key pieces of evidence that China is heading for a crash.
