E3 Countries Launch Process to Reimpose Sanctions on Iran

Strategic Insights -

The European countries of Britain, Germany, and France have initiated a process to reimpose United Nations sanctions on Iran over its nuclear program, sparking condemnation from Russia and China. The move, known as the "snapback mechanism," was launched on Thursday in response to accusations that Iran has violated a 2015 deal aimed at preventing the development of a nuclear weapons capability. The decision opens a 30-day window for the international community to adopt a new UN resolution to continue sanctions relief and prevent penalties from being reimposed. Iran has vowed to respond to this "unlawful and unwarranted measure," with its Foreign Minister Abbas Araghchi calling the move "unjustified" and "lacking any legal basis."
