France says U.S. must comply fast with WTO Boeing ruling

France said on Wednesday that the United States must comply with a World Trade Organisation (WTO) ruling this week against U.S. tax breaks for Boeing , and that failure to do so would give the EU legal basis for retaliatory measures. The WTO said this week that a tax break from Washington state to help Boeing develop its new 777X jetliner was a prohibited subsidy, in a setback for the U.S. planemaker as it eyes victory in a parallel case against Airbus .
