The United Kingdom hosted virtual talks with representatives from more than 40 countries, including France, Germany, Italy, Canada and the United Arab Emirates, to begin forming a coalition aimed at restoring navigation through the Strait of Hormuz, the BBC reported on April 2. The United States did not attend.

Escalating disruptions in the Strait of Hormuz have followed Iranian attacks on commercial vessels in retaliation for U.S.-Israeli strikes, effectively halting transit through a critical route for global oil and liquefied natural gas flows. The meeting follows growing pressure from Washington, with U.S. President Donald Trump urging other countries to take responsibility for securing the strait and criticizing European allies for their lack of support. Tensions over the strait have further strained transatlantic relations, highlighted by the Trump administration's most explicit threat yet of a potential U.S. withdrawal from NATO on April 1, alongside reports that Trump threatened to halt weapons supplies to Ukraine via NATO procurement mechanisms.
