Both remain below the threshold of combat. They differ in whether the dispute is resolved or simply remains open.

A 57% chance the coming year stays below the threshold of combat — a fragile young ceasefire after the worst border fighting in years, the limited-action tail elevated while it holds.

Strategic timeline
Historical
  1. 1962The International Court of Justice awards the Preah Vihear temple to Cambodia.
  2. 2000Thailand and Cambodia sign a memorandum on land-boundary demarcation.
  3. 2008UNESCO lists Preah Vihear as a World Heritage site, and nationalist protests and military deployments follow.
  4. 2008–11Periodic armed clashes occur between Thai and Cambodian troops near the temple.
  5. 2011Cambodia asks the International Court of Justice to interpret its 1962 judgment.
  6. 2013The court rules that the 1962 judgment gave Cambodia the whole Preah Vihear promontory.
  7. 2014The two agree to joint border patrols and to pull back heavy weapons near the temple.

Curated for strategic significance, not completeness. The timeline provides context; the Foundation Paper explains the assessment.
