Nobody should defend China's human rights record. However, I think linking energy and human rights won't solve either problem, and confuses the issues. I've been impressed that China is securing oil reserves with lawyers and contracts and dollars, and appalled that the US is trying to do it with armies.

America's military option to secure oil supplies has proven unworkable. America's energy security will be contingent on its own good behaviour: good public policy, energy conservation, and observing the rule of international law.

Ah, yes, China has been so good about securing territory with lawyers and contracts and dollars; all those Tibetans got such a great deal in the buyout that Taiwan's populace is urging an acceptance of the takeover bid!

The evidence shows that China will use contracts and lawyers when they expect other nations (namely us) to respect them.  They'll use arms to take over other countries, as they have before.  China's methods are not principled, they are cynical and deserve even less respect than you accord to the US.
