U.S.-China trade spat interrupts dollar's dip, for now

The signs of a U.S. and global recovery -- and a revived appetite for risk -- have weakened the dollar about three percent during the past two weeks versus the world's other major currencies. But now a U.S.-China trade spat threatens to reverse that trend.

After the Obama administration slapped an up to 35 percent tariff on China's exported tires, China indicated it would restrict U.S. imports of chicken and auto products, and demanded trade talks to resolve the dispute, The Wall Street Journalreported Monday.
