"Nothing in today's report even suggests that the (WTO) compliance panel found that the amount has decreased," said a USTR spokesman. "There is accordingly no basis for Airbus's assertions that the report 'implies' that the U.S. countermeasures should be reduced by $2 billion."

USTR earlier said it could increase tariffs on a wider range of European goods after the WTO rejected European Union claims that it no longer provides subsidies to Airbus. Airbus had said Washington should slash its authorized tariffs of $7.5 billion to $5.5 billion since the WTO dropped its previous references to its A380 causing lost sales to Boeing.
