European leaders seize G7 summit to address Hormuz reopening as Iran weighs fees Allies from the G7 group will seek common ground on Monday with US President Donald Trump at a summit in France following the fresh agreement between Washington and Iran. Macron said in a post on Instagram overnight that the summit will examine the "consequences" of the Iran accord, which is due to be signed in neighbouring Switzerland on Friday, in terms of the implications for Lebanon , the lasting reopening of Hormuz and Iran's ballistic activities. He later added in a post on X that a UK-France mission to aid the reopening of the Strait of Hormuz had its assets in place and was "ready to be deployed".
