“Iran is harmed, but also harmed is U.S. credibility — as a country and as a party to any international negotiations,” Fu Cong, China’s ambassador to the United Nations, told China’s state broadcaster on Sunday.

China said the U.S. attack on Iran's nuclear facilities had damaged Washington's credibility and warned the situation "may go out of control", its state broadcaster reported, following a U.N. Security Council meeting on Sunday.

US Secretary of State Marco Rubio has called on China to prevent Iran from closing the Strait of Hormuz, one of the world's most important shipping routes. His comments came after Iran's state-run Press TV reported that parliament had approved a plan to close the Strait but added that the final decision lies with the Supreme National Security Council.
