U.S. Secretary of State Marco Rubio has called on China to use its influence to stop Iran from closing the vital Strait of Hormuz, following U.S. strikes on Iranian nuclear sites. Speaking on Fox News, Rubio warned that shutting the strait would cause serious global economic disruption, especially affecting China due to its heavy dependence on Gulf oil. He urged Beijing to intervene, calling the move “economic suicide” for Iran. His statement follows reports that Iran’s parliament approved a measure to block the strait, a key route for 20% of the world’s seaborne oil trade.
