Cambodia's Military Buildup and Border Conflict with Thailand

Overview of the Conflict
In June 2025, Chinese military aircraft, specifically Y-20s, transported significant military supplies to Cambodia, coinciding with escalating tensions between Cambodia and Thailand over a disputed border area. This arms shipment included rockets, artillery shells, and mortars, which were subsequently moved to Cambodia's contested border with Thailand. The conflict erupted into a five-day war in late July, with both nations blaming each other for initiating hostilities.
Key Developments Leading to War
The Thai intelligence documents reviewed indicate that the Chinese weapons were stored at the Ream Naval Base before being relocated to the border. Analysts suggest that Cambodia's military buildup, which included constructing new roads and a military base near the Preah Vihear temple, was a strategic move to assert its position against Thailand. Nathan Ruser from the Australian Strategic Policy Institute noted that this buildup represented a significant shift in Cambodia's military posture.
Official Responses and Statements
Cambodia's Secretary of State for Defense, Lt. Gen. Rath Dararoth, acknowledged the arms shipments but characterized the Thai intelligence reports as misleading, asserting that the movements coincided with a joint military exercise with China. However, this exercise had concluded weeks prior. The Cambodian government has consistently claimed that it does not seek conflict with Thailand, despite its military preparations.
Criticism and Opposition
Critics argue that Cambodia's military actions, supported by Chinese arms, reflect a deliberate strategy to alter the status quo along the border. Human rights organizations, such as Fortify Rights, have highlighted the significant role of Chinese-made weapons in the conflict, raising concerns about their use in aggressive military actions against Thailand. Analysts have pointed out that Cambodia's military buildup was more proactive compared to Thailand's largely defensive posture.
Conflicting Reports and Gaps
There are discrepancies regarding the extent of military preparations and the nature of the conflict. While Cambodia insists it does not have an offensive military doctrine, evidence suggests a concerted effort to fortify its military capabilities. Additionally, while Cambodia has sought intervention from the International Court of Justice to resolve the conflict, Thailand has rejected this approach, complicating diplomatic efforts.
Implications of the Conflict
The conflict underscores the growing military ties between Cambodia and China, which has become Cambodia's primary arms supplier. This relationship raises questions about regional stability and the potential for further escalation in Southeast Asia. Analysts warn that the situation could lead to a broader confrontation, particularly as both nations continue to enhance their military capabilities.
