What a great example of inter-dependence from the FP article, my emphasis:
Electricity consumption usually spikes over the summer, as people turn on their air-conditioners to cope with the seasonal heat. But this year, many Chinese appear to be braving the high temperatures to economize. China's ports are piled high with coal that should be roaring in the country's power plants.... Now it looks as if China has imported more fuel than it needs, as hard-pressed citizens, businesses, and factories cut their electricity consumption in order to reduce their bills.

The national price of coal has already dropped 10 percent since late last year. This drop could further dent the global economy, which would in turn cool demand for Chinese exports even more. That's globalization for you: A Chinese person turns off the air-conditioning, and the world economy catches a cold.
