French President Emmanuel Macron and British Prime Minister Keir Starmer will co-chair a conference Friday in Paris, bringing together non-belligerent nations willing to participate in a mission in the Strait of Hormuz “when security conditions allow.”

Other participants will take part via videoconference, Macron’s office said. European and other partners are ready to contribute to a “purely defensive mission aimed at restoring freedom of navigation in the Strait of Hormuz,” the statement said.
