Myanmar Civil War
Myanmar's junta pursues constitutional legitimacy while ASEAN re-engagement erodes the resistance's isolation strategy.
Thailand and Cambodia fought their deadliest border clash in over a decade in July 2025, with skirmishes between the Royal Thai Armed Forces and Royal Cambodian Armed Forces killing at least 17 people and displacing civilians across three Thai provinces.
The fighting traces back to a 1962 International Court of Justice ruling that awarded the Preah Vihear temple to Cambodia, a verdict Thailand never fully accepted. The two countries are not formally allied with rival powers, but Cambodia leans on China while Thailand is a US treaty ally.
ASEAN, built on consensus, has no real tool to force a settlement between two of its own members.
Trajectory
The ceasefire is holding but the bilateral architecture around it is collapsing.
Thai PM Anutin and Cambodian PM Hun Manet met in Cebu in May 2026, extending ASEAN monitoring to July and tasking foreign ministers with confidence-building talks, but no substantive progress was made.
It matters because the interstate continues to tie down the main belligerents, pull in outside backers, and shape the security balance across asia-pacific.
Analysis
MoU 44 cancellation is structurally irreversible in the near term given PM Anutin's nationalist political base; no replacement bilateral framework has been proposed.
Cambodia's UNCLOS compulsory conciliation signal is a coercive venue shift: it forces Bangkok to engage on procedural terms it cannot control or accept a default internationalization of a dispute it has historically.
Both militaries are institutionalizing counter-drone doctrine following fiber-optic drone use in the 2025 clash, with Thailand establishing a dedicated UAS warfare center and battalion.
Historical Context
The International Court of Justice awarded the Preah Vihear temple to Cambodia; Thailand never fully accepted the ruling, leaving surrounding border territory contested and a source of enduring tension.
Vietnamese forces ousted the Khmer Rouge, installing a government in Phnom Penh that Thailand opposed, militarizing the border region and turning it into a Cold War proxy frontier throughout the 1980s.
The Paris Peace Accords ended Cambodia's civil war and normalized Thai-Cambodian relations, but the Preah Vihear border demarcation was left unresolved.
UNESCO's World Heritage listing of Preah Vihear reignited the territorial dispute; both countries deployed troops to the border area, and Cambodia's move drew sharp protests from Bangkok.
Sporadic firefights between Thai and Cambodian forces around Preah Vihear and the nearby Ta Moan and Ta Krabey temples escalated into sustained clashes between 2008 and 2011, killing approximately 25 soldiers and displacing thousands of civilians.
The ICJ ruled again that Thailand must withdraw troops from a 4.6 sq km disputed zone around Preah Vihear, reaffirming Cambodian sovereignty; Thailand complied under protest but bilateral mistrust deepened.
Hun Sen transferred power to his son Hun Manet as Cambodian Prime Minister, consolidating dynastic rule and signaling continuity of Cambodia's assertive posture on border and territorial issues.
A new clash erupted along the Thai-Cambodian border in July, killing at least 17 people and forcing populations across three Thai provinces to seek shelter, marking the deadliest border violence in over a decade.
No external sponsors. ASEAN attempting mediation. China has relations with Cambodia; US with Thailand (treaty ally).
