Energy exporters beware: China is looking out for No. 1

Mr. Putin’s apparent assumption is that China will take as much oil, gas and coal as Russia can pump or dig out of the ground. He may be right in the short term, even the medium term.

It’s not just that China’s growth rates are slowing; it’s that China is embracing the green revolution a lot faster than the oil and coal barons realize.
