An interesting snippet in a Wall Street Journal article focusing China's rising oil imports and its increasing naval power:
China has used other tools to protect its oil supplies. Starting late last year, Iran repeatedly threatened to close the Straits of Hormuz if Western countries kept adding new sanctions; Hormuz is the world’s biggest chokepoint for oil shipments. U.S. officials warned Tehran to back off for weeks. Then, in late January, Chinese premier Wen Jiabao warned Iranian leaders not to even think about interfering with shipping through the Straits. Obama administration officials said that the warning, coming from one of the few countries that have dealings with Tehran, carried considerable weight.
I'm very interested what China would have done if Iran closed the Straits. For once the US might have been able to sit back and enjoy the action. Increasingly when China says, "don't even think about it," they mean it. Stay out of Wen Jiabao's way.
