LAUSANNE, Switzerland — Large US and Iranian delegations led by Secretary of State John Kerry and Iranian Foreign Minister Mohammad Javad Zarif arrived here March 15 for a crucial week of meetings. The meetings aimed at reaching a political agreement on a final nuclear accord by the end of the month, as the White House issued a new veto threat for congressional legislation it says could jeopardize a deal.
Ahead of Kerry’s arrival, lead US negotiators Undersecretary of State Wendy Sherman met with her counterparts, Iranian Deputy Foreign Ministers Abbas Araghchi and Majid Ravanchi, and their teams. US Secretary of Energy Ernest Moniz and Atomic Energy Organization of Iran (AEOI) chief Ali Akbar Salehi also held technical meetings.
