The EU announced that “the Joint Commission of the JCPOA will convene in a physical format on 29 November in Vienna… [to] continue the discussions on the prospect of a possible return of the U.S. to the JCPOA and how to ensure the full and effective implementation of the agreement by all sides”. A U.S. diplomatic spokesperson indicated that “it remains possible to quickly reach and implement an understanding on a mutual return to compliance… This window of opportunity will not be open forever, especially if Iran continues to take provocative nuclear steps”.
