Thailand has rejected mediation efforts from third countries to end the ongoing conflict with Cambodia, insisting that Phnom Penh cease attacks and resolve the situation only through bilateral talks,

Thailand and Cambodia exchanged heavy artillery fire for a second day on Friday as their worst fighting in over a decade intensified and spread to new areas.

The Cambodian government described the action as a serious violation of international law, including the United Nations Charter and the ASEAN Charter. They added that the Thai aggression "not only endangers peace and stability along our shared border but also demonstrates utter disregard for regional norms and international legal obligations."
