Martin Hutchinson's piece on the Chinese economy bubble is worth your time:
Savers are not permitted to take money out of China, and their huge savings prop up an overvalued stock market and a bond market that is comparable in size to the freely flowing international bond market. Private sector companies are either youthful fly-by-night operations or dubiously privatized state behemoths. Prices are still largely administered, and investment flows mostly to the politically connected rather than to the economically attractive. Education is relatively poor outside the main population centers, and land ownership is still restricted.
China is thus much more like pre-1941 Japan than post-1950 Japan and its economic inefficiencies are correspondingly greater. Because of those economic inefficiencies, the chances remain high of a meltdown far before China has achieved Western living standards.
