July 24, 2025
1 min read

Background & Recent Trigger

  • Historic Friendship: Once among the world’s friendliest nations, Cambodia and Thailand shared strong diplomatic ties.
  • Recent Escalation:
    • On May 28, a Cambodian soldier was killed in a clash at the Emerald Triangle (Thailand-Cambodia-Laos border).
    • Both sides blame each other for starting the violence.
    • Cambodia sent troops and heavy weapons; Thailand reinforced border security.

Tit-for-Tat Measures

  • Military & Political Moves:
    • Troop build-up, though some withdrawal on June 8 to ease tension.
  • Economic & Media Retaliation:
    • Thailand threatened to cut electricity & internet to Cambodia; restricted Thai workers from Cambodian casinos.
    • Cambodia banned Thai TV/movies, cut cross-border internet, and blocked Thai produce imports (June 17).
  • Legal Dispute:
    • Cambodia took the case to the International Court of Justice (ICJ).
    • Thailand rejected ICJ jurisdiction, insisting on bilateral talks.

Historical Context

  • Colonial-Era Borders:
    • Borders mapped by French colonizers (1863–1953); 1907 map placed Preah Vihear Temple in Cambodia, disputed by Thailand.
  • Past Clashes:
    • 1959 & 1962: ICJ ruled temple belongs to Cambodia.
    • 2008–2011: Military skirmishes displaced 36,000 people.
    • 2013: ICJ reaffirmed Cambodia’s sovereignty over the temple, but surrounding areas remain disputed.
  • Joint Boundary Commission (JBC) exists since 2000 but has made little progress.

Political Dynamics

  • Leadership Factor:
    • Thai PM Paetongtarn Shinawatra vs Cambodian PM Hun Manet—both children of influential leaders (Thaksin Shinawatra & Hun Sen).
    • Personal family ties complicate public perception of negotiations.
  • Thai Military’s Role:
    • Seen as a potential destabilizer; analysts warn border tensions could be used to stoke nationalism or justify a coup, echoing past political upheavals in Thailand.

What’s Next?

  • Peaceful Resolution Uncertain: ICJ involvement vs Thailand’s push for bilateral talks prolongs deadlock.
  • Risk of Escalation: Nationalist pressures and military posturing could trigger renewed conflict.
  • Economic & Social Fallout: Cross-border trade, labor movement, and regional ASEAN stability could be affected.
