Top diplomats including U.S. Secretary of State Marco Rubio, Russia's Sergei Lavrov, and EU foreign policy chief Kaja Kallas gathered Thursday at the security-focused ASEAN Regional Forum hosted by the 11-member Association of Southeast Asian Nations in Manila. The event occurs 12 days after the collapse of a Middle East ceasefire, with China's Vice Foreign Minister Hua Chunying stating the world has entered a period of turbulence affecting energy and food supplies. The forum addresses regional security amid an ASEAN economy valued at approximately $3.8 trillion.
