34. We resolve to work together to counter the proliferation of weapons of mass destruction and renew global arms control efforts. We emphasize our support for the ongoing diplomatic efforts and negotiations in Vienna aimed at facilitating the return of the United States to the Joint Comprehensive Plan of Action (JCPOA) as well as the full and effective implementation of the deal by Iran and the United States. We share serious concerns about steps taken by Iran, which are inconsistent with the JCPOA. The European Union and the United States recognize that, alongside the return to full and effective implementation by Iran of its nuclear related commitments, the lifting of sanctions constitutes an essential part of the JCPOA. The JCPOA remains critical to ensuring the exclusively peaceful nature of Iran’s nuclear program and to upholding the global nuclear non-proliferation architecture.
