But that is precisely the opposite of what they are doing isn't it? First, they aren't selling us oil. They are indeed driving up oil and all other essential energy and commodities resources necessary for great power status...in direct competition against us. Indeed, they tried to snap up UNOCAL and divest our country of a major set of oil supply for the future.
Second, their sales to us instead of supporting our infrastructure, are destructive....they are taking U.S. manufacturing plant, relocating it to their country, either directly with their own purchases, or with the willing accomplices amongst those who would rather switch than fight.
The only advantage the U.S. receives is temporary, and potentially costly in the extreme to undo the damage already done. But it will have to be, as soon it becomes inescapably clear that China doesn't care about remaining a footstool for their western stooges...and won't. They are simply biding their time to reverse the roles.
We're importing 14,000 barrels of oil per day from China (here).
