From USTR:
Today, U.S. Trade Representative Ron Kirk announced that the United States is requesting that the European Union (EU) enter into consultations regarding the notification it made on December 1, 2011, claiming to have fully complied with the World Trade Organization (WTO) ruling that subsidization of Airbus aircraft is contrary to WTO rules. The United States has reviewed carefully the limited information in that notification. It appears to show that the EU has not withdrawn the subsidies in question and has, in fact, granted new subsidies to Airbus’ development and production of large civil aircraft.
The United States is also requesting authorization from the WTO Dispute Settlement Body (DSB) in Geneva to impose countermeasures annually in response to the EU’s claim that it fully complied with the ruling in this case. The amount of the countermeasures would vary annually, but in a recent period would have been in the range of $7-10 billion. This step will preserve U.S. rights, but any actual imposition of countermeasures would not occur until after further WTO proceedings.
