BANGKOK, June 14, 2025 (BSS/AFP) - Officials from Thailand and Cambodia met Saturday in Phnom Penh, an AFP journalist saw, as the Southeast Asian neighbours sought to resolve a long-running border dispute that last month devolved into clashes.

Troops from the two countries exchanged fire on May 28 in an area known as the Emerald Triangle, where the borders of Cambodia, Thailand and Laos meet, with one Cambodian soldier killed.

The Thai and Cambodian armies both said they had acted in self-defence, but agreed to reposition their soldiers to avoid confrontations.

Thailand has tightened border controls with Cambodia in recent days, while Cambodia ordered troops on Friday to stay on "full alert".

Officials from the two countries had agreed to resolve the spat at Saturday's meet in the Cambodian capital Phnom Penh.

Foreign ministry adviser Prasart Prasartvinitchai was leading the Thai delegation, while Chea Lam, minister of state in charge of the Secretariat of Border Affairs, headed the Cambodian contingent.

Neither side commented ahead of the talks.

The row dates to the drawing of the 800-kilometre (500-mile) frontier, largely done during the French occupation of Indochina.

The region has seen sporadic violence since 2008, resulting in at least 28 deaths.

Cambodian Prime Minister Hun Manet announced earlier this month that Cambodia would file a complaint with the International Court of Justice (ICJ) over four disputed border areas, including the site of the latest clash.

The ICJ ruled in 2013 that a disputed area next to Preah Vihear temple belonged to Cambodia, but Thailand says it does not accept the ICJ's jurisdiction.
