U.S. Goes After China at WTO as Pressure Mounts

The Obama administration, facing growing complaints in Washington that it hasn’t persuaded China to increase the value of its currency, filed two trade cases against the world’s largest exporter of goods.

The complaints at the World Trade Organization yesterday -- one on payment-processing companies and the other on steel duties -- followed demands in Congress hours earlier that the U.S. push China to accept a stronger yuan. Today, Treasury Secretary Timothy F. Geithner is scheduled to appear before the same lawmakers to discuss China’s trade and its currency.
