(MENAFN- The Arabian Post)

A civilian death and multiple injuries have reignited tensions along the frontier between Cambodia and Thailand, casting doubt on a peace understanding signed in October. Cambodia reported that one resident of Prey Chan village in its Banteay Meanchey province was killed and three others wounded when gunfire erupted across the border near Thailand's Sa Kaeo province. Cambodia's Prime Minister informed that the incident occurred in the late afternoon, and described it as unprovoked action by Thai forces. Thai military representatives asserted that Cambodian troops had initiated the firing, prompting Thai soldiers to respond with warning shots.

The incident follows Thailand's suspension of implementation of a bilateral peace declaration signed with Cambodia on 26 October. Thailand cited a landmine blast in Sisaket province-injuring Thai soldiers-as justification for pausing its commitments under the accord. Cambodia rejected the blame for the blast and affirmed its continued adherence to the deal. The ceasefire had been brokered after heavy fighting in July that resulted in dozens of fatalities and large-scale displacement.

The October agreement was designed to ease a longstanding border dispute rooted in colonial-era map discrepancies and contested temple sites along the roughly 817-km frontier. Observers had described the deal as fragile from the outset because it did not fully address the core territorial claims or establish a robust monitoring mechanism. The latest exchange of gunfire underlines the limits of confidence between the parties. Local witnesses from Prey Chan described a burst of shots lasting about 10–15 minutes, forcing families to flee into wooded areas; Thai soldiers in Sa Kaeo province reported responding to incoming fire.

Military and diplomatic sources say Thailand's government is now treating the peace understanding as effectively suspended unless Cambodia meets conditions to demonstrate non-hostility. Thailand's prime minister visited border troops this week and publicly declared that unless Cambodian forces halt cross-border strikes and mines are removed, the deal cannot advance. Cambodia has appealed for restraint, while regional observers warn that the breakdown of dialogue could prompt renewed large-scale clashes.

Humanitarian implications are emerging in the border zone. Cambodian officials said hundreds of villagers in Prey Chan and adjacent communes have begun evacuation efforts, driven by fear of further exchanges and unexploded ordnance. The July confrontations had displaced over 100,000 people and inflicted widespread damage to civilian infrastructure, including hospitals and schools. The November shooting has revived memories of those earlier displacements.

Regional and international players are watching closely. While the United States, China and the Association of Southeast Asian Nations offered to facilitate mediation during the July escalation, Thailand insisted on bilateral negotiation and rejected third-party involvement. Analysts say that if the current accord collapses altogether, the risk of escalation into multi-domain hostilities-including air strikes and artillery-will rise significantly. Cambodia's government reiterated its commitment to the peace deal, but said that aggressive incursions by Thai forces would force a defensive response.

Traders and investors are taking note. Cross-border commerce between Thailand and Cambodia has been growing in agriculture, tourism and manufacturing sectors; disruption of the frontier stability could hamper supply-chain operations and investment flows. The prospect of uninsured losses in border-province industries has heightened concern among business groups.

Diplomatically, the episode raises questions about both countries' ability to manage nationalist pressures and security-force accountability. The pre-existing temple-territory dispute has been amplified by domestic politics in both capitals, making concessions difficult. The recent exchange has reignited calls within Thailand for a stronger military posture and within Cambodia for international monitoring of Thai troops.
