Regional stability: Ceasefire Agreement between Thailand and Cambodia
In a significant move towards peace and stability, Cambodian Defense Minister Tea Seiha and Thai Defense Minister Nattaphon Narkphanit exchanged documents at a joint declaration ceremony on December 27, 2025. Both nations have agreed to fully resume the ceasefire implementation under the supervision of ASEAN observers. Effective from 12:00 PM, the agreement commits both forces to refrain from unprovoked firing, troop advancement, or mobilization near the border. This landmark decision not only promises stability for local communities but also alleviates safety concerns for international tourists visiting both kingdoms.
