A look at the relations between the erstwhile superpowers the US and USSR, especially the trade relations show that they never had great trade ties. Trade with the USSR was barely 1% of total trade of the US. The superpowers didn't have much economic leverage with each other. The only thing that they shared was hatred for each other. Compare this with the US and the pretender to being the next super power,China. The US is chinas largest trading partner with trade heavily loaded in favor of China by a ratio of 1:4. But then China is making all efforts to box in the US and the west and asserting itself aggressively against the west which is a case of biting the hand that feeds you. In the quest of strategic dominance both economic and military, how do you reconcile the fact that you want to take down your biggest customers? If the US and Europe sanction China, as they import more than they export from china once matters get outta control, how will china go about it? China wants hi tech stuff from the west esp arms to develop weapons that will be aimed at the west itself!!! I cannot understand this Chinese thinking.
