US President Donald Trump presided over the signing of a peace agreement between Thailand and Cambodia at the opening of the ASEAN Summit in Malaysia. The deal, signed by the leaders of both countries, officially ends months of deadly border clashes and includes provisions for the release of Cambodian soldiers and withdrawal of heavy weapons from the border. The agreement builds on a ceasefire brokered earlier this year and establishes mechanisms for future conflict prevention. The summit also saw East Timor admitted as the newest member of the regional bloc, with leaders celebrating the milestone and discussing broader economic and trade issues.
