If they don't play by the rules, why should we ?

This question, and all relevant variations, is what the free traders do not grasp. An American manufacturer of farm equipment is not doing business simply a Chinese agricultural enterprise. He is doing business with the Chinese government. The imbalance becomes all the more clear when the American manufacturer learns the Chinese have cloned his equipment and are selling it under their own brand.
$55 oil might cause them to re-consider, too. Once China decided to peg its currency to the dollar, they lost any control they might have had over their own currency. When the U.S. dollar declines against the Euro, the Chinese yuan declines against the Euro even if there is nothing in the Chinese economy that would otherwise cause such a decline.
