51 countries for an international summit on the Strait of Hormuz

Paris & London – April 18, 2026 – In a dramatic display of multilateral resolve, France and the United Kingdom convened leaders from 51 countries in an emergency international summit on the Strait of Hormuz yesterday, April 17, issuing a unified ultimatum for the immediate and unconditional reopening of the strategic waterway.

The summit, hosted jointly in Paris, underscored the international community’s determination to defend freedom of navigation, uphold international law, and protect global economic stability and energy security. The gathering—one of the largest diplomatic interventions on maritime security in a decade—followed weeks of escalating tensions and the recent blockade of the strait, through which approximately 20% of global oil consumption passes.

In a joint communiqué released after the April 17 meeting, the 51 nations expressed “strong support for a comprehensive diplomatic settlement to the conflict through negotiations,” insisting that “diplomacy must prevail.” However, the tone of the closing statements left little doubt that patience is wearing thin.

“The right of transit passage without restrictions or tolls is the bedrock of international trade,” the communiqué read. “Freedom of navigation means navigation must be free.”

Immediate Reopening Demanded

The summit’s first and most urgent demand was for the “unconditional, unrestricted, and immediate re-opening of the Strait of Hormuz.” Shortly after the communiqué was released on April 17, diplomatic sources confirmed that behind-the-scenes negotiations had yielded a breakthrough: authorities controlling the strait announced they would comply, reopening the waterway effective immediately.

Leaders welcomed the announcement but stressed that the reopening “must endure.” They warned that the disruption to global energy security, supply chains, and economic stability “must end, for the benefit of communities right across the world, in particular for the poorest and most vulnerable.” Participating nations committed to coordinating economic responses and avoiding protectionist actions.

Defensive Multinational Mission Established

In the most significant operational development, France and the United Kingdom confirmed the immediate establishment of an independent, strictly defensive multinational mission to protect merchant vessels, reassure commercial shipping operators, and conduct mine clearance operations.

The mission—to be activated as soon as conditions permit following a sustainable ceasefire agreement—will operate in full accordance with international law and in consultation with relevant regional states. Officials described it as a direct response to recent attacks on civilian shipping and the deployment of sea mines in key shipping lanes.

“The UK, France, and all our partners will draw on our collective diplomatic, economic, and military capabilities to support freedom of navigation,” the statement read.

Several nations have already indicated readiness to contribute military assets, logistical support, financial resources, or political solidarity. The UK and France will jointly coordinate military planning with contributing nations, with the UK scheduled to host the next leaders’ meeting in this format.

Support for Maritime Industry and Seafarers

The summit also confirmed strong support for the International Maritime Organisation (IMO) in its vital work to ensure the safety of seafarers and vessels. Leaders pledged continued engagement with shipping operators, insurers, and industry bodies to help commercial traffic resume operations as soon as conditions permit.

Global Reaction

The announcement drew swift international reaction. NATO’s Secretary General called the initiative “a measured and lawful response to an unacceptable threat to global commerce.” The European Commission welcomed the reopening of the strait, while oil prices, which had spiked dramatically over the past two weeks, fell sharply in after-hours trading.

A senior French diplomatic official, speaking on condition of anonymity, told reporters: “This is not about escalation. This is about ensuring that no single waterway can be held hostage to paralyze the world economy. The message is clear: the international community will act, together.”

The British Prime Minister, speaking at the closing press conference on April 17, added: “We have chosen the path of unity, law, and defensive action. The strait is open—and with the resolve of 51 nations behind us, it will remain so.”
