The European Union has called on the International Atomic Energy Agency (IAEA) to give full consideration to any proliferation implications and risks arising from the AUKUS nuclear submarine partnership, in a statement delivered at the IAEA Board of Governors meeting in Vienna on 11 June 2026. The EU stressed the importance of respecting the IAEA Secretariat's independent mandate to engage with member states on safeguards and verification matters, and looked forward to further reporting by the IAEA Director General once an arrangement with Australia is finalised.
The statement, delivered under agenda item 11 on AUKUS as any other business, was aligned with by Albania, Bosnia and Herzegovina, Iceland, Montenegro, North Macedonia, Norway, the Republic of Moldova, and Ukraine. The EU reiterated its strong attachment to the Nuclear Non-Proliferation Treaty (NPT) and the integrity of the non-proliferation regime, noting that the IAEA is the competent body to ensure full, impartial, independent and objective implementation of safeguards.
The EU noted Australia's stated commitment not to produce nuclear fuel, enrich uranium or reprocess spent fuel in connection with any nuclear propulsion programme. The statement did not express outright opposition to AUKUS but emphasised the need for rigorous safeguards and transparency. This is the first time the EU has formally addressed the AUKUS partnership at the IAEA Board of Governors, reflecting growing European concern over the proliferation implications of naval nuclear propulsion transfers to a non-nuclear-weapon state.
Stakeholder impact and trade-offs
The EU's position balances support for Australia's rights under the NPT with the need to uphold the non-proliferation regime. For Australia, the statement signals that the EU will closely scrutinise the safeguards arrangements, potentially adding diplomatic pressure to ensure maximum transparency. For the United Kingdom and the United States, the EU's call for IAEA oversight may complicate the trilateral partnership by inviting broader international scrutiny. For the IAEA, the EU's backing strengthens its mandate to negotiate a safeguards agreement with Australia, but also places it at the centre of a politically sensitive issue. For non-proliferation advocates, the EU's stance is a positive step, though some may view it as insufficiently critical of the precedent set by transferring naval nuclear propulsion technology to a non-nuclear-weapon state.
Expected follow-up
The EU indicated it would take appropriate action once an arrangement between Australia and the IAEA is finalised. The IAEA Director General is expected to report further on the matter, and the Board of Governors may revisit the issue at future sessions.
