Despite diplomatic engagements, restoring the so-called Iran nuclear agreement continues to be hindered by political and technical differences, the UN political and peacebuilding chief told the Security Council on Thursday. In the landmark accord, formally known as the Joint Comprehensive Plan of Action (JCPOA) - reached in 2015 between Iran, the United States, China, France, Russia, and the United Kingdom - Iran agreed to dismantle much of its nuclear program and open its facilities to international inspections in exchange for sanctions relief. In 2018, then-President Trump withdrew the US from the agreement and reinstated the sanctions. "Achieving the landmark JCPOA took determined diplomacy. Restoring it will require additional effort and patience," said UN political affairs chief, Rosemary DiCarlo. Although the landmark Joint Commission to restore the Plan resumed in November 2021, she acknowledged that despite their determination to resolve the issues, the US and other participants are yet to return to "full and effective implementation of the Plan, and [Security Council] resolution 2231". Together with the Secretary-General, she urged Iran and the US to "quickly mobilize" in "spirit and commitment" to resume cooperation under the JCPOA. They welcomed the reinstatement by the US in February of waivers on nuclear non-proliferation projects and appealed to the country to lift its sanctions, as outlined in the Plan, and extend oil trade waivers. Together they also called on Iran to reverse the steps it has taken that are inconsistent with its nuclear-related commitments under the Plan. While the International Atomic Energy Agency (IAEA) has been unable to verify the stockpile of enriched uranium in Iran, it estimates that there is currently more than 15 times the allowable amount under the JCPOA, including uranium enriched to 20 and 60 percent, which Ms. DiCarlo called "extremely worrying". Moreover, on 8 and 20 June, IAEA reported that Iran had started to install additional advanced centrifuges at the Fuel Enrichment Plant at Natanz and began feeding uranium into advanced centrifuges at the Fuel Enrichment Plant at Fordow. In his latest report, IAEA Director General Rafael Grossi, informed the Council that the UN agency's ability to verify and confirm the peaceful nature of Iran's nuclear activities are key to the JCPOA's full and effective implementation. Iran's decision to remove site cameras and place them and the data they collected under Agency seals, "could have detrimental implications". Bilateral and regional initiatives to improve relationships with Iran remain "key" and should be encouraged and built upon, according to Ms. DiCarlo. Additionally, Member States and the private sector are urged to use available trade instruments to engage with Iran and Tehran is requested to address their concerns in relation to resolution 2231 (2015) on its nuclear issues. The senior UN official also drew attention to annex B of the resolution, updating ambassadors in the Council on nuclear-related provisions, ballistic missiles and asset freezing. "The JCPOA was a triumph for non-proliferation and multilateralism," said the UN political affairs head. However, after many years of uncertainty, she warned that the Plan is now at "a critical juncture" and encouraged Iran and the US to build on recent momentum to resolve the remaining issues. "The Secretary-General is convinced there is only one path to lasting peace and security for all Member States, and that is the one based on dialogue and cooperation," she said. "We hope that diplomacy will prevail". Iran nuclear deal: a summary What is the Iran nuclear deal? The 2015 "Joint Comprehensive Plan of Action" (JCPOA), sets out rules for monitoring Iran's nuclear program, and paves the way for the lifting of UN sanctions. Which countries are involved? Iran, the five members of the Security Council (China, France, Russia, UK, US), plus Germany, together with the European Union. What is the UN's involvement? A UN Security Council resolution to ensure the enforcement of the JCPOA, and guarantee that the UN's atomic energy agency, the IAEA, continues to have regular access to and more information on Iran's nuclear program, was adopted in 2015. Why is the deal at risk? The current US administration pulled out of the deal in 2018 and re-imposed sanctions. In July 2019, Iran reportedly breached its uranium stockpile limit, and announced its intention to continue enriching uranium, posing a more serious proliferation risk. Olof Skoog, Head of the European Union Delegation to the UN, speaking in his capacity as the Coordinator of the Joint Commission established by the JCPOA, to the Security Council, recognized the negative economic consequences that the US' withdrawal from the JCPOA has had on Iran but affirmed that restoring the agreement is "the only way" for the country to reap its full benefits. He reminded that the Plan would comprehensively lift sanctions, encourage greater international cooperation, and allow Iran to reach its "full economic potential". "It is, therefore, important to show the necessary political will and pragmatism to restore the JCPOA," said Ambassador Skoog who, while acknowledging the sense of urgency, counseled against "escalatory steps" and to preserve sufficient space for the diplomatic efforts to succeed. — UN News
