The mafias and anarchist dystopia described by GP exists in China. In my nearly 9 years here I have received some reflections of this (random pick: I have spent a night near a children factory near Hong-Kong).
But saying that China, or even Wenzhou is an anarchist dystopia is wrong. It is similar to describing New-York with a picture from the Bronx during a "bad day".
On the opposite, saying that Wenzhou and other places are economic paradise where anyone can do whatever they want without the central government even being aware of this is false. These coastal regions have been set up as an experiment on economic opening by Deng Xiaoping, and Jiang Zemin and Hu Jintao have been in fact "chosen" by him, in order to continue in the same tracks. You can count on the current government to care about these places, and to be ready to do whatever is needed if it goes too far.
What is happening in China right now is impressive, and such a fast mutation is probably unseen in the world history at this scale.
It will have a great impact on the world. Will it be for the best or for the worst? I can't be sure, but what I know is that knowing better each other, increasing exchanges between West and East, is the best and only way we have to push a little, just a little bit, away from the worst case scenario.
