Overview
- Bangkok said any halt to hostilities must begin with Phnom Penh and called for sincere cooperation on border demining, rejecting claims that a new ceasefire is in place.
- Clashes continued across several provinces with artillery, rockets, drones and Thai air operations, while Cambodia said F-16 strikes hit near displaced-person shelters and inside Siem Reap province close to Angkor Wat.
- Thailand moved to restrict Cambodia’s supplies by stopping fuel shipments through the Chong Mek crossing into Laos and labeling a Thai-vessel "high-risk" zone in the Gulf of Thailand rather than imposing a full naval blockade.
- Officials reported at least 32 deaths and roughly 800,000 people displaced; Thailand confirmed its first civilian killed on its side, and Cambodia reported at least 15 civilian deaths, later updated to 17.
- Cambodia closed the Poipet land crossing, leaving 5,000 to 6,000 Thai citizens seeking repatriation, as ASEAN scheduled emergency talks for December 22 following continued fighting despite a US-announced truce.
