"But exchange rates do affect the pattern of growth, and it is in China’s own interest to restructure and move away from high dependence on export-led growth. China recognizes that its currency needs to appreciate over the long run, and politicizing the speed at which it does so has been counterproductive. (Since it began revaluing its exchange rate in July 2005, the adjustment has been half or more of what most experts think is required.) Moreover, starting a bilateral confrontation is unwise.
Since China’s multilateral surplus is the economic issue and many countries are concerned about it, the US should seek a multilateral, rules-based solution. Imposing unilateral duties after unilaterally labeling China a “currency manipulator” would undermine the multilateral system, with little payoff. China might respond by imposing duties on those American products effectively directly or indirectly subsidized by America’s massive bailouts of its banks and car companies.
No one wins from a trade war. So America should be wary of igniting one in the midst of an uncertain global recovery – as popular as it might be with politicians whose constituents are justly concerned about high unemployment, and as easy as it is to look for blame elsewhere. Unfortunately, this global crisis was made in America, and America must look inward, not only to revive its economy, but also to prevent a recurrence."
