The EU voiced regret on Monday that Washington would reopen its World Trade Organisation (WTO) case against subsidies for aircraft maker Airbus but stopped short of announcing a resumption of its case against Boeing. "This is a disappointing move by the United States given the proposals for a negotiated solution the EU side made on Friday," European Commission spokeswoman Claude Veron-Reville said in a statement carried by Rueters. "The EU will make its own position known tomorrow." The United States, seeking to defend Boeing, said it would reactivate its WTO case against billions of dollars in subsidies by European Union government subsidies for Airbus after latest efforts to reach a negotiated settlement with Brussels failed, Reuters reported. --SP 2349 Local Time 2049 GMT
