G20 leaders discuss formula to ease currency tension

World leaders discussed economic imbalances, currency tensions and trade protection at the G20 Summit in Seoul on Friday. The G20 hopes to use the Summit to recapture unity forged in the depths of the crisis two years ago in order to ease currency tensions generated by imbalances between cash-rich exporting nations and debt-burdened importers. But the second and final day of the meet looked set to open on a sour note after days of squabbling over the wording of their final statement, with Washington taking the flak for the Federal Reserve's bond-buying spree to revive the U.S. economy, and giving it back to China for holding the Yuan down.
