U.S. national-security adviser Jake Sullivan pressed Chinese Foreign Minister Wang Yi to use his country's influence to help rein in Iran's support for Huthi rebels attacking Red Sea merchant vessels, according to a senior Biden administration official on January 27. Beijing has told Washington it is raising the issue with Iran, the U.S. official said, adding they are waiting to see whether China does so and how effective the outreach will be. The Chinese and U.S. diplomats met for two days of meetings in Bangkok.
