Chinese President Xi Jinping has ended a six-week silence over the ongoing war in Iran, vowing that Beijing will play a "constructive" role in efforts to bring the conflict to a close. China, which was not party to the war's outbreak, has been treading carefully to balance its longstanding strategic partnership with Tehran against broader interests across the Middle East and beyond. The move signals that Beijing — a major global power that has largely stayed in the shadows on this conflict — is now signalling a more active diplomatic posture as international pressure to resolve the war mounts.
