UK Hosts 40-Nation Coalition to Reopen Strait of Hormuz Amid Iran Blockade

Apr 3, 2026

Britain convened a virtual summit on April 2, 2026, with over 40 countries to coordinate reopening the Strait of Hormuz after Iran established a de facto blockade following a war that began February 28, 2026. Iranian forces have attacked at least 23 commercial vessels and effectively control the strait, which normally carries one-fifth of the world's oil, causing energy prices to soar and forcing nations to tap strategic reserves. The United States notably declined participation, with President Trump arguing Europe should handle the crisis since they depend more on the route, while France's Macron called military force unrealistic and advocated for diplomatic coordination with Iran. The UN Security Council prepared to vote on a Bahrain-sponsored resolution authorizing military force, though coalition members at the Thursday talks reached no concrete solutions beyond planning further discussions with military planners.
