United Nations: Reaching a negotiated settlement regarding Iran’s nuclear program is the best option for the international community

United Nations Under-Secretary-General for Political and Peacebuilding Affairs, Rosemary DiCarlo, said: “Despite significant differences between the parties concerned on the way forward regarding… By Security Council Resolution No. 2231 of 2015 And the Joint Comprehensive Plan of Action, all of which continued to emphasize the importance of a diplomatic solution, and expressed their general willingness to communicate with each other for this purpose.”.

This came in a briefing to the Security Council, today, Tuesday, regarding developments related to the implementation of International Resolution 2231, noting that despite the intensification of diplomatic efforts during the second half of 2025, no agreement was reached on the ways forward regarding the Iranian nuclear program.

The UN official recalled that, according to what is known as the “rapid return mechanism,” and since the Council did not adopt a resolution to continue ending the sanctions measures within 30 days of the letter submitted by Germany, France, and the United Kingdom regarding commitments under the joint plan of action, the previous sanctions were reapplied on Iran on September 27, 2025.

She explained that several concerned member states rejected the validity and effectiveness of the process of re-imposing sanctions, while some members specifically stressed that the process was procedurally and legally flawed.

A necessary framework

The Under-Secretary-General also referred to the International Atomic Energy Agency’s November report which stated that Iran had stopped implementing its nuclear program obligations under the Joint Comprehensive Plan of Action as of 23 February 2021.

However, the agency is still able to verify and monitor some of these commitments through activities carried out under Iran’s safeguards agreement within the framework of the Treaty on the Non-Proliferation of Nuclear Weapons, she said.

She added that “The Agency has concluded that a jointly agreed framework, with the support of the countries concerned, is necessary to ensure that Iran’s nuclear program is exclusively peaceful.”.

Regarding the remaining restrictive measures set out in Annex B of Resolution 2231, specifically those related to nuclear activities and diversions, DiCarlo said that no allegations of violations of these provisions had been received during this reporting period.

But she noted that the Security Council had received six notifications of restrictive measures related to nuclear activities for certain activities consistent with the Joint Comprehensive Plan of Action.
