Thai security officials have raised the alarm over a potential resurgence of conflict along the border with Cambodia, warning that recent intelligence points to a significant build-up of Cambodian forces and advanced weaponry that could precipitate further hostilities.

The alert comes as Thailand navigates the aftermath of its general election and seeks to maintain stability along a frontier that has seen periodic clashes and a suspended ceasefire after violent escalations last year.

According to security sources, reconnaissance has identified Cambodia’s acquisition of sophisticated anti-aircraft systems that Thailand perceives as capable of neutralising its historical air superiority and altering the tactical balance on the disputed border.

Officials characterised this development as deeply concerning, noting that it could embolden Phnom Penh to initiate a fresh round of strikes, potentially reigniting long-dormant violence.

The warning underscores the fragility of the peace established after an earlier ceasefire, which was uneasily brokered following months of fighting that included artillery exchanges and air operations affecting civilian areas.

Last year’s clashes displaced tens of thousands and led to casualties on both sides before diplomatic efforts helped calm tensions temporarily.

Thailand’s military and security leadership have responded by placing border patrols and strategic units on heightened readiness, intensifying surveillance, and reinforcing defensive positions in eastern provinces adjoining Cambodia.

The government has emphasised its commitment to safeguarding national sovereignty while keeping diplomatic channels open, even as it prepares for the possibility that negotiations alone may not avert further confrontation.

The situation remains dynamic, with regional partners and international observers urging restraint and dialogue.

Officials in Bangkok have stressed that any escalation could have widespread humanitarian and economic ramifications, especially in communities close to the border that suffered significant disruption during past clashes.

The next days will be closely watched for signals from both capitals as Thailand balances deterrence with efforts to avoid a wider conflict.
