Executive Summary
Thailand’s use of airstrikes against Cambodian military positions marks the most serious military escalation along the border in over a decade.
Landmine explosions and border disputes are causing a confrontation that has disrupting cross-border trade and vital infrastructure. Cambodia has responded by suspending imports of Thai goods and banning Thai media content. Thailand has threatened to cut electricity and internet services to Cambodian towns near the frontier.
Despite attempts at de-escalation, recent events heighten geopolitical risks in the Asia-Pacific region, alarming neighbouring countries and international actors.
Key Takeaways
- Thai airstrikes signal a shift to a high-intensity confrontation, with implications for border security and infrastructure continuity.
- Cambodia’s limited military capability and economic dependence on Thailand constrain its ability to respond effectively.
- The crisis disrupts trade, energy supplies, and international cooperation.
Background Information
Military tensions between Thailand and Cambodia escalated sharply following two landmine incidents that injured six Thai soldiers between 16 and 23 July. In response, Thai forces launched airstrikes targeting Cambodian military positions along the disputed border. The use of air power in this crisis is unprecedented, marking a dramatic departure from past engagements, which were primarily limited to ground combat.
Following a series of border clashes that killed at least eight Thai people, Thailand launched airstrikes. Cambodia warned it would “respond decisively.” Tensions rose as diplomatic relations worsened; both nations recalled diplomats, reduced ties, and imposed economic sanctions on each other.
Thailand’s 361,000 active-duty personnel outnumber Cambodia’s military by over three to one, and its equipment is superior across the board (according to the document Military Balance 2025). Its air force operates 11 moderns Swedish Gripen fighters, US-made F-16s and F-5s, and US Cobra and Black Hawk helicopters. The army fields modern Chinese VT-4 tanks, a large artillery fleet, and participates in regular multinational exercises, including Cobra Gold.
Cambodia, conversely, possesses no air force capable of engaging in combat. Its ground forces rely on 200 ageing Chinese and Soviet tanks and a limited artillery inventory. Its rotary-wing capability is restricted to older transport helicopters. The Cambodian military suffers from limited operational range, inadequate logistics, and weak air defences.
Economically, Thailand tightened border control and threatened to cut off electricity and internet access to Cambodian border towns. In retaliation, Cambodia stopped importing Thai produce and banned Thai television and movies. Disputed border areas, especially the Emerald Triangle and the Preah Vihear temple region, are key to bilateral trade and contain vital infrastructure.
Geopolitical Scenario
Thailand’s military escalation follows Prime Minister Paetongtarn Shinawatra’s suspension, triggered by a leaked conversation with Hun Sen, Cambodia’s ex-leader. The historically powerful Thai military seems to be seizing this political opportunity to assert greater independence. Using air power signals a strategic shift toward deterrence, aimed at preventing further Cambodian military action in contested areas.
Cambodia, led by Hun Manet but still under the influence of Hun Sen, faces a dilemma. To preserve its standing on the world stage, the nation must avoid a conflict it lacks the military strength to sustain. Domestically, the legitimacy of Hun Manet’s still-forming government depends partly on the public’s perception of its ability to protect national sovereignty.
The Preah Vihear temple area and its surroundings continue to be volatile regions, marked by past violence in 2008 and 2011. Cambodia previously attempted to resolve the border dispute through the International Court of Justice, but Thailand’s non-recognition of the court’s jurisdiction over certain areas limits legal options.
Indicators to Monitor
- Thai deployment of air assets or further strikes across other contested zones.
- Cambodia’s mobilisation of reserves or paramilitary units to reinforce border positions.
- Disruption of electricity and internet supply to Cambodian towns by Thai authorities.
- Expansion of Cambodian trade bans on Thai products or escalation to infrastructure sabotage.
- Public demonstrations, conscription moves, or nationalist rhetoric in both capitals.
Conclusion
Thailand’s air attacks represent a major military escalation, increasing the dangers along the Thai-Cambodian border. Cambodia is economically and militarily outmatched, limiting its ability to respond proportionally. Urgent concerns focus on the durability of energy supplies, the stability of border communities, and the potential for more military engagements.
The strategic competition between the United States and China places their bilateral conflict within a broader Asia-Pacific geopolitical struggle.
The United States and Thailand have a long-standing security partnership, with extensive military cooperation and exercises that bolster Bangkok’s regional influence. However, China’s increasing economic and political backing of Cambodia reinforces Phnom Penh’s allegiance to Beijing.
This rivalry increases the chance that local conflicts could get drawn into a larger power struggle, making de-escalation and regional stability harder to achieve.
