Working groups have been trying to come to solutions for both issues, and the European Union, which chairs the Joint Commission meetings, said a third group was set up Tuesday “to start looking into the possible sequencing of respective matters.”The EU''s foreign policy chief, Josep Borrell, said Tuesday that he had spoken last week with U.S. Secretary of State Antony Blinken and Iranian Foreign Minister Mohammad Javad Zarif. Borrell said that while he couldn''t go into details, there was “a real goodwill from both parties to reach an agreement, and that is good news.”“They have been moving from general to more focused issues, which are, clearly, on one side sanctions lifting and, on the other side, nuclear implementation issues,” he said.
