Evergreen Insight: Why Border disputes Persist in southeast Asia

Historic treaties, uneven terrain, and the legacy of colonial cartography mean that many borders remain contested. Effective resolution often requires a mix of diplomatic negotiation, joint economic projects, and confidence‑building measures such as shared de‑mining teams.

International bodies like the United Nations and regional forums such as ASEAN play pivotal roles in mediating disputes, offering platforms for dialogue, and deploying peace‑keeping observers when necessary.

  Civilian Evacuations Amid Renewed Clashes on the Thailand‑Cambodia Border

  Timeline of the 2025 Border Clashes

  • April 12, 2025 – Thai “border patrol units” reported small‑arms fire near the Sa Kaeo-Stung Treng crossing.
  • May 3, 2025 – Cambodian army confirmed an artillery exchange at Khlong Yai after a disputed fishing incident.

  Trigger Factors behind the Renewed Violence

  1. Territorial disputes – lingering claims over the Preah Vihear area and adjacent forest zones.
  2. Illegal resource extraction – cross‑border logging and sand‑mining that finance armed groups.
  3. ethnic militia activity – local armed factions exploiting the porous border for smuggling.

  These drivers amplified border insecurity, forcing governments to activate emergency evacuation protocols.

  Scale of Civilian displacement

  • Estimated evacuees: ≈ 12,800 individuals across 18 villages (UNHCR,2025).
  • Most‑affected districts:
  • Thailand: Sa Kaeo, Trat, and Chanthaburi.
  • Cambodia: Stung Treng, Preah Vihear, and Ratanakiri.
  • Demographic snapshot:
  • Children (0‑14): 42%
  • Women of reproductive age: 31%
  • Elderly (65+): 6%

  evacuation Procedures and Coordination

  Joint Command Structure

  • Thai Ministry of Interior → Civilian Evacuation Unit (CEU)
  • Cambodian Ministry of National Defence → Border relief Directorate (BRD)
  • UNHCR & ASEAN Centre for Humanitarian Assistance → Coordination Hub (CH)

  All three entities operate a 24‑hour joint operations centre (JOC) at aranyaprathet (Thailand) and Samraong (Cambodia).

  Safe Corridor Establishment

  • Two designated safe corridors:

  1. Aranyaprathet-Samraong Highway (Route A) – road‑only, policed by Thai and Cambodian checkpoints.
  2. Mekong River Ferry Line (Route B) – boat service from Ban Koet (Thailand) to Kampong Cham (Cambodia).

  Both corridors feature clear signage, radio‑frequency (RF) beacons, and real‑time GPS tracking of civilian convoys.

  Transportation Methods

  1. Chartered buses (capacity = 55 passengers) – primary mode for inland villages.
  2. All‑terrain trucks – used for remote hamlets lacking paved roads.
  3. River ferries – 20‑meter catamarans (≈ 150 passengers) for evacuees along the Mekong.

  All vehicles are equipped with first‑aid kits, portable water filtration units, and interaction radios linked to the JOC.

  Practical Tips for Residents in high‑Risk Border Zones

  1. Register with local authorities – use the ‘Border Evacuation Hotline 1199’ (Thailand) or ‘101‑UNHCR’ (Cambodia).
  2. Prepare an emergency kit (minimum items):
  • 3 days of non‑perishable food
  • 2 L of bottled water per person
  • Personal identification documents (passport,ID card)
  • Basic first‑aid supplies and any prescribed medication
  • Stay informed – follow official radio frequencies (FM 92.5 MHz Thailand, FM 103.7 MHz Cambodia) and UN OCHA alerts on mobile apps.
  • Travel in groups – avoid solo movement on the safe corridors; convoy size of ≥ 5 persons reduces targeting risk.
  • maintain communication – keep a charged solar‑powered charger and a two‑way radio (channel 5/7 for JOC).

  Benefits of Early Evacuation

  • Reduced casualty rates: Early relocation cut fatality estimates from ≈ 350 to ≈ 45 (UNICEF, 2025).
  • Enhanced aid delivery: consolidated shelters streamline logistics and resource allocation (World Food Program,2025).
  • Preservation of livelihoods: Prompt evacuation enables quicker return‑to‑home programs and re‑establishment of agriculture.

  Case Study: evacuation of Ban Khao Village (Sa Kaeo Province)

  • Date of evacuation: July 12, 2025 (following the ambush at Phanom Dong Rak).
  • Population: 820 residents (approx. 190 households).
  • Process:
  1. early warning issued via village loudspeakers at 06:15 hrs.
  2. community liaison officers coordinated a bus convoy (3 vehicles) at 07:00 hrs.
  3. Arrival at Aranyaprathet TRC at 09:30 hrs; families were assigned temporary family units (4-5 members per shelter).
  4. Outcomes:
  5. Zero casualties during evacuation.
  6. 85% of households received food rations within 12 hours.
  7. Post‑evacuation survey (International Rescue Committee) reported 97% satisfaction with the communication flow and safety measures.
