Joint statement on Strait of Hormuz by European nations, Japan, Canada

What Happened

On March 19, 2026, the leaders of the United Kingdom, France, Germany, Italy, the Netherlands, Japan, and Canada issued a joint statement on the Strait of Hormuz, later published on the UK government's official portal.
The statement condemned "in the strongest terms" Iranian attacks on unarmed commercial vessels, targeting of civilian oil and gas infrastructure, and the de facto closure of the strait by Iranian forces.
It explicitly invoked UNSC Resolution 2817 and the freedom of navigation provisions of UNCLOS, framing Iran's actions as violations of international law.
The signatories expressed "readiness to contribute to appropriate efforts to ensure safe passage through the Strait" and welcomed nations "engaging in preparatory planning" — signalling support for a potential naval coalition without formally committing military assets.
On energy markets, the joint statement welcomed the IEA's coordinated strategic petroleum reserve release and committed to working with producing nations to increase output and support the most affected nations through the UN and international financial institutions.
Canada's inclusion expanded the original six-nation grouping to seven, reflecting the G7 democratic coalition's alignment — notably absent were the US (which initiated the Iran war) and the broader EU bloc.

The G7 and Collective Diplomatic Statements

The Group of Seven (G7) is an informal bloc of the world's seven largest advanced economies: Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. The G7 holds no permanent secretariat or legally binding powers; its influence derives from the combined economic and political weight of members, and from the normative signal that collective G7 statements send to the international community.

The G7 was formed in 1975 as the G6, following the 1973 oil crisis and global recession — making the Hormuz crisis a direct echo of the G7's founding emergency.
Russia was suspended from the then-G8 in 2014 following the annexation of Crimea, reverting the group to G7.
G7 joint communiqués and statements (issued at summits or at ministerial levels) are the primary diplomatic tool of the grouping — non-binding but politically significant.
In the 2026 Hormuz crisis, the US is the initiating belligerent; the remaining G7 members (UK, France, Germany, Italy, Japan, Canada) issued this statement as a bloc, reflecting a degree of diplomatic distancing from US military action while broadly supporting the coalition's goal of reopening the strait.
The EU as a bloc also issued a parallel statement through the European Council, providing overlapping but distinct diplomatic signals.

Connection to this news: The joint statement represents the G7's (minus the US) attempt to assert a rules-based-order framework around the crisis — positioning themselves as defenders of international law rather than co-belligerents, while leaving open the possibility of military contribution through "appropriate efforts."

UNSC Resolution 2817 and the UN Security Council's Role in Maritime Crises

The UN Security Council (UNSC) is the UN's primary organ for the maintenance of international peace and security, with five permanent members (P5: US, UK, France, China, Russia) each holding veto power. UNSC resolutions are legally binding on all UN member states when passed under Chapter VII of the UN Charter.

Chapter VI resolutions call for peaceful settlement of disputes; Chapter VII resolutions authorise enforcement measures including economic sanctions and military action.
A P5 veto can block any UNSC resolution — in the Hormuz crisis, Russia and/or China are expected to veto any resolution that authorises military force against Iran.
UNSC Resolution 2817 (cited in the joint statement) pertains to the legal framework for maritime security and freedom of navigation in the context of the current crisis — its specific text and passage details were not publicly available at time of writing, but its invocation signals that the joint statement has a formal UNSC legal anchor.
Historical precedent: UNSC Resolution 598 (1987) called for a ceasefire in the Iran-Iraq War and the restoration of free navigation in the Persian Gulf — setting a precedent for UNSC involvement in Hormuz-related crises.
UNSC Resolution 1816 (2008) authorised naval operations against Somali piracy in the Gulf of Aden — another precedent for multilateral maritime enforcement action.

Connection to this news: By invoking an explicit UNSC resolution, the seven-nation joint statement grounds its demands in binding international law, strengthening the legal case for potential enforcement action and creating diplomatic costs for China and Russia if they continue to shield Iran.

The 1982 UN Convention on the Law of the Sea (UNCLOS) is the foundational treaty governing all maritime activity, including navigation rights through international straits. Part III of UNCLOS establishes the "transit passage" regime for straits used for international navigation, which provides stronger protections than the standard "innocent passage" right applicable in territorial seas.

Transit passage (UNCLOS Articles 37–44) allows all ships and aircraft to pass through international straits continuously and expeditiously in their "normal modes of operation."
Unlike innocent passage (which coastal states can suspend for security reasons in their territorial seas), transit passage through international straits cannot be suspended or impeded by the coastal state.
Submarines may transit submerged; warships transit without prior notification — making transit passage rights significantly broader than innocent passage.
Coastal states bordering an international strait may designate traffic separation schemes (as in the Hormuz strait's two-mile lanes), but cannot block transit.
Iran has historically contested these provisions, arguing that the strait falls under its sovereignty and that it has the right to control access — a position rejected by the international legal mainstream.
UNCLOS has been ratified by 168 states; the US has not ratified it but accepts most of its provisions as customary international law.

Connection to this news: The joint statement's explicit citation of UNCLOS freedom of navigation provisions is a deliberate legal signal — framing Iran's blockade not merely as a hostile act but as a violation of treaty law that all 168 UNCLOS signatories have a stake in challenging.
