The European Union's foreign policy chief said on Monday he hoped the United States would respond positively as early as this week to an EU proposal that aims to save a 2015 nuclear deal with Iran.
Josep Borrell also said that Iran had given a "reasonable" response to the proposal, which follows 16 months of fitful, indirect U.S.-Iranian talks with the EU shuttling between the parties. The contents of the proposal have not been made public.
