Vitaliy Katsenelson has posted an excellent article on the chinese currency bubble. I have previously talked about this impending issue. Vitaliy's explanation is well articulated and is an enjoying read.
To add my comments to it, it appears that the newspapers do not stress enough about this topic but they really should. This is something that will likely be the cause of the next market upheaval. Unfortunately, the media and government is more interested in creating short-term consumption demand rather than to look at the real long-term problem out there.
