Months of simmering tensions between Cambodia and Thailand have exploded into armed conflict, in the heaviest fighting between the Southeast Asian neighbours in over a decade.
Prime Minister Anwar Ibrahim of Malaysia, the current chair of Southeast Asian bloc ASEAN, in which Thailand and Cambodia are also members, urged calm and said he would speak to leaders of both countries to peacefully resolve their dispute. China also expressed concern at the fighting and said it was willing to play a role in promoting de-escalation.
