In brief
The E3 states are prepared to reimpose strict sanctions unless Iran engages in discussions by August's end.
The foreign ministers of Germany, France, and the UK have communicated to the United Nations their readiness to reinstate sanctions on Iran concerning its nuclear ambitions if discussions do not commence by the end of August. Known collectively as the E3, the nations indicated they could activate a "snapback" mechanism which reverts to prior sanctions if Iran fails to engage in dialogue.They recently offered Iran an extended deadline for negotiations through the end of August, a proposal that has yet to receive a response from Tehran. Last month, Iran expressed willingness to negotiate further, but only contingent upon lifting existing sanctions and recognition of its civilian nuclear rights.This tension follows preliminary discussions between E3 representatives and Iranian diplomats held in Istanbul last month. In a joint letter addressed to UN Secretary-General António Guterres, Jean-Noël Barrot from France, David Lammy from the UK, and Johann Wadephul from Germany underscored their intent to impose harsh sanctions should Iran refrain from constraining its nuclear activities.On Tuesday, the E3 reaffirmed that their offer for an extension remains unacknowledged by Iran. "We have stressed that if Iran remains unwilling to find a diplomatic resolution by the end of August 2025, or does not take advantage of this extension, the E3 are ready to trigger the snapback mechanism,” the letter outlined. The countries reaffirmed their commitment to employing all diplomatic avenues to prevent Iran from acquiring nuclear weapons, a claim Iran has consistently denied.Kazem Gharibabadi, Iran's Deputy Foreign Minister, asserted in July that the reinstatement of sanctions would be "entirely illegal." The sanctions originally imposed on Iran’s nuclear program were lifted in 2015 following the signing of the Joint Comprehensive Plan of Action (JCPOA) alongside the E3, US, Russia, and China, where Iran agreed to limit its nuclear capabilities and allow international inspections.However, the US withdrew from the JCPOA in 2018, under President Trump's administration, claiming it fell short of curbing Iran's pathway to a nuclear bomb, which led to the reinstatement of all US sanctions. In retaliation, Iran progressively escalated its breach of set nuclear limits. As of May, the UN nuclear watchdog, the International Atomic Energy Agency (IAEA), reported Iran possessed over 400kg of uranium enriched to a 60% purity level - significantly above civilian requirements and approaching weapons-grade status.Faced with escalating tensions, including Israeli strikes on Iranian nuclear sites, Iran's parliament halted cooperation with the IAEA in June, inciting an intense series of diplomatic conflicts. Subsequent to these developments, E3 nations intensified their warnings regarding Iran's diminishing compliance with the IAEA regulations. Efforts for commentary from the UK Foreign Office have been made, while the Iranian mission to the UN has yet to respond.
