BRUSSELS, Jan 15 (Reuters) - The European Union's trade chief said on Thursday she was preparing a case against the United States at the World Trade Organisation over Washington's revision of a list of EU goods hit with retaliatory duties.
"It is clear that this move by the U.S. administration means that we will have no choice but to start preparations in order to take this to the WTO," EU Trade Commissioner Catherine Ashton said in a statement. (Reporting by Darren Ennis, editing by Dale Hudson)
