The leaders of France and the U.K. gathered dozens of countries — but not the United States — on Friday to push forward plans to reopen the Strait of Hormuz, a key oil route choked off by the U.S.-Israeli war on Iran.

The Paris meeting is part of attempts by sidelined nations to ease the impact of a conflict they didn't start and haven't joined, but that has sent the global economy reeling. After the war started on Feb. 28, Iran effectively shut the narrow strait though which a fifth of the world's oil usually passes.
