Remember how notoriously inaccurate such predictions are. Remember how they screamed that Japan will eclipse the US economy in the 80s. Take into account the similarities between Japan and China. Compare how the things said about Chinese economy now are nearly identical to the statements made about Japan thirty-twenty years ago. Take note of the real estate and stock bubble, that killed Japan, and the worries of the massive Chinese gov't spending which is feared to lead to another bubble.

Now, China could very well avoid the fate of Japan, and it is very unlikely it will fall like that. But still, an export-driven economy is a dangerous thing, as the days of mercantilism have long passed and it is recognised that a balanced economy is superior to the China/Russia/Germany -esque export economies.

Then again, with China's population, it is difficult to imagine any other fate for such a nation... Either a total collapse, or magnificent dominance. In any case, such Louis-esque enthusiastic rhetorical flourish on a certain subject is always to be taken with a grain of salt, no matter how eloquently it is presented, such as in this case.
