Multilateral arms control, disarmament and non-proliferation

We aim to bolster the multilateral non-proliferation and disarmament regimes, particularly the nuclear Non-Proliferation Treaty. We provide ideas, analysis and research resources that support the efforts of serving diplomats in the NPT process. We also focus on specific regional challenges to the multilateral non-proliferation and disarmament system, including the future of nuclear diplomacy with Iran, and (in partnership with our sister Asia-Pacific Leadership Network) understanding Indo-Pacific perspectives on strategic risks. The ELN’s work has supported the P5 Dialogue, with a view to encouraging the NPT nuclear weapon states to engage jointly in strategic risk reduction. We also work to support the CTBT and encourage its entry into force and want to deepen the understanding of the concept of irreversibility in nuclear disarmament.

Turning down the heat: Addressing the growing salience of nuclear weapons

At the 2025 NPT Preparatory Committee in New York this month a key issue likely to spark debate is the increasing salience of nuclear weapons. All five nuclear-weapon states under the NPT are increasing the role and significance of nuclear weapons in their military and security policies, at odds with the commitments accepted under the NPT. This new policy brief from the ELN’s Protecting the Nuclear Non-Proliferation Treaty project examines this challenge and offers recommendations for states to address it within the NPT framework.

A fragile opening: Iran, the US, and the high-stakes return to diplomacy

Talks between Tehran and Washington are set to take place on Saturday in Oman. Hamidreza Azizi writes that much of Iran’s political spectrum is cautiously optimistic about negotiations, reflecting a recognition of Iran’s military and economic constraints, and a desire to avoid war while securing relief from crippling sanctions. This pragmatic approach may signal a rare opportunity to pursue a deal that addresses concerns over Iran’s nuclear program while averting another regional conflict, but the potential for miscalculation remains high.

Meeting report: Iran, Europe and the US – new approaches to nuclear diplomacy

In January 2025, the ELN with support from the Rockefeller Brothers Fund (RBF), convened a roundtable to discuss ways forward for a resumption of Iran-US nuclear negotiations. European, American, Asian, and Middle East experts discussed the role of Gulf actors in developing a new deal, Iran’s shift in priorities under President Pezeshkian, and the implications of the changes in the regional architecture as a result of the war in Gaza.

Focused Multilateralism: How China and Germany can better engage on arms control, disarmament and non-proliferation

Engaging China on multilateral arms control, disarmament and non-proliferation has become more urgent, but also more difficult. Even in times of increased competition between China, Russia, and the US, Europeans have agency and will need to up their level of ambition in pursuing their own interests in making multilateral instruments more resilient. ELN Policy & Research Director Oliver Meier and Michael Staack call for focused, substantive, and flexible dialogues between Europeans and Chinese.
