Statement from the Royal Government of Cambodia: A Call for Lasting Peace

 

Statement from the Royal Government of Cambodia: A Call for Lasting Peace

The Kingdom of Cambodia stands firm in its unwavering commitment to peace, stability, and good neighborly relations in Southeast Asia. We have consistently pursued all diplomatic avenues to resolve the long-standing border dispute with the Kingdom of Thailand through peaceful means and in accordance with international law.

On July 24, 2025, our nation endured an unprovoked and premeditated military assault that resulted in the tragic loss of civilian lives and the displacement of tens of thousands of our citizens. Cambodia's armed forces were compelled to act in self-defense, a fundamental right enshrined in the Charter of the United Nations, to protect our sovereignty and our people. We have steadfastly rejected the use of force as a means of resolving disputes and have worked tirelessly to de-escalate the situation, despite the immense suffering inflicted upon our people.

We have called for the immediate and unconditional release of our soldiers held in Thai custody and have appealed to the international community for support. Our commitment to a peaceful resolution is demonstrated by our appeals to the United Nations Security Council (UNSC), our referral of the disputed areas to the International Court of Justice (ICJ), and our full cooperation with mediation efforts led by our ASEAN partners, particularly Malaysia.

Cambodia urges Thailand to honor its ceasefire obligations, cease all aggressive actions and provocations, and return to the negotiating table in good faith. We call upon all parties to respect the principles of sovereign equality, mutual respect, and the rule of law. The path to a lasting solution is not one of military confrontation but of sustained, honest dialogue.

Research and Analysis of Cambodia's Diplomatic Stance

Cambodia's response to the 2025 border conflict with Thailand has been defined by a clear and concerted effort to leverage international diplomacy and legal frameworks. From the outset, the Cambodian government, led by Prime Minister Hun Manet, has framed the conflict not as an equal military confrontation, but as a case of Thai aggression that must be addressed through established global and regional institutions.

The Role of International Bodies: Following the initial clashes in May and the major escalation in July, Cambodia immediately took several key steps:

• Appealing to the UN: Cambodia's Permanent Representative to the UN formally requested a UNSC meeting, outlining Thailand's alleged violations of international law and calling for immediate intervention. This move was crucial for securing international attention and pressure for de-escalation.

• Seeking ICJ Adjudication: Cambodia has consistently expressed its willingness to submit the border dispute to the International Court of Justice. This stance aligns with the country's preference for legal, rather than military, solutions, reinforcing its image as an international law-abiding nation. This is a contrast to Thailand, which has previously refused to acknowledge the ICJ's jurisdiction on this matter.

• Engaging ASEAN: Cambodia has actively participated in and supported the mediation efforts of ASEAN, accepting the ceasefire proposal brokered by Malaysia. The subsequent General Border Committee (GBC) meetings have been a key forum for Cambodia to address ongoing ceasefire violations, such as the alleged deployment of barbed wire and landmines by Thai forces in disputed areas.

Humanitarian and Political Considerations: Beyond diplomacy, Cambodia's strategy has been deeply rooted in a humanitarian narrative. The government has consistently highlighted the immense human cost of the conflict, citing civilian casualties and the mass displacement of over 300,000 people. This focus on the humanitarian crisis serves to rally international support and underscore the devastating consequences of Thailand's military actions.

Politically, this approach allows Cambodia to cast itself as the victim of aggression, seeking only to defend its territory and its people. By appealing to multilateral bodies and upholding international law, Cambodia is able to counter the military and economic power imbalance between the two nations, shifting the focus from the battlefield to the diplomatic arena. While the ceasefire remains fragile, Cambodia's consistent diplomatic efforts are a testament to its long-term commitment to a peaceful and just resolution to the conflict.

The Role of Heavy Weaponry in the 2025 Thailand-Cambodia Conflict

 

The Role of Heavy Weaponry in the 2025 Thailand-Cambodia Conflict

The latest escalation in the long-standing border dispute between Thailand and Cambodia, which came to a head in July 2025, was defined by a significant and unprecedented use of heavy weaponry. The five-day conflict marked a dramatic and devastating departure from previous skirmishes, which typically involved small-arms fire and localized troop movements. The use of modern, high-impact firepower not only caused a humanitarian crisis but also drew international condemnation and complicated diplomatic efforts.

Escalation and the Use of High-Impact Arms

The direct armed conflict, which erupted on July 24, 2025, followed months of simmering tensions and a series of smaller incidents, including a fatal skirmish in May and landmine incidents that injured Thai soldiers. On the day the conflict broke out, both nations accused the other of firing first. The fighting quickly escalated, with both sides deploying heavy, high-impact military assets.

Thailand’s response was particularly defined by its use of air power and artillery. Thai forces deployed F-16 fighter jets to conduct airstrikes against what they designated as military targets within Cambodia. On the ground, they also utilized artillery barrages to strike Cambodian border posts and civilian settlements. The Thai army has since confirmed the use of both cluster munitions and white phosphorus shells. While Thai officials maintained these weapons were used in a manner compliant with international law and were restricted to military targets, the use of such armaments sparked international concern, particularly from human rights organizations. In turn, Cambodia was also accused by Thailand of launching indiscriminate attacks on Thai territory using BM-21 rockets.

Humanitarian and Economic Impact

The humanitarian toll of this heavy firepower was severe. The intense fighting reportedly killed at least 38 people, with both sides reporting a high number of civilian casualties, including children. The use of explosive weapons with wide area effects in populated zones caused immediate harm and long-term damage to critical infrastructure, including schools and hospitals. The conflict displaced hundreds of thousands of civilians from their homes on both sides of the border, with some estimates placing the number of displaced at over 300,000.

Beyond the human cost, the conflict caused significant economic disruption. The closure of key border checkpoints sharply reduced import-export volumes, with cross-border trade in June falling by 23% year-on-year. Economic forecasting centers estimated that the full closure of the five major border points alone cost Thailand approximately 11 billion baht per month in lost exports. This economic fallout highlighted the interconnectedness of the two economies and the high stakes of the military confrontation.

Diplomatic Fallout and International Response

The escalation prompted swift and concerned reactions from the international community. The United Nations Security Council convened an urgent, closed-door meeting on July 25, during which all 15 member states called for de-escalation, maximum restraint, and a peaceful resolution. The conflict also tested the cohesion of the Association of Southeast Asian Nations (ASEAN). Malaysia, as the ASEAN Chair, stepped in to mediate a ceasefire proposal, which was reportedly accepted by both sides, albeit with some initial reluctance from Thailand.

Despite the ceasefire taking effect on July 28, the diplomatic dispute has continued. Cambodia has appealed to the UN and ASEAN, alleging ongoing ceasefire violations and human rights abuses by Thai forces. Thailand, in turn, has denied these claims and has stated its intention to sue Cambodian leaders for violating its sovereignty. The conflict has not only strained diplomatic relations but has also revealed a deep-seated mistrust, fueled by historical grievances and competing claims over colonial-era maps and ancient temples. The involvement of external powers, including the United States and China, who both have significant influence in the region, was crucial in pushing for a truce, underscoring the broader geopolitical implications of the conflict.

The clash serves as a stark reminder of the devastating consequences when long-standing border disputes, compounded by domestic political tensions, escalate into modern warfare. While a fragile ceasefire is in place, the path toward a lasting solution remains uncertain, contingent on sustained dialogue and a willingness to move past the entrenched positions of the past.

A Fragile Peace: The Ongoing Thailand-Cambodia Ceasefire

 

A Fragile Peace: The Ongoing Thailand-Cambodia Ceasefire

The ceasefire between Thailand and Cambodia, which came into effect on July 28, 2025, remains highly volatile. Despite the cessation of major armed conflict, both nations continue to accuse one another of violating the terms of the agreement, highlighting a deep-seated mistrust rooted in decades of historical and territorial disputes.

Historical Context of the Conflict

The roots of the conflict extend back to colonial-era treaties. The Franco-Siamese treaties of 1904 and 1907 established the border, but ambiguities and a French-drawn map that deviated from the agreed-upon watershed line led to a long-running dispute. While the International Court of Justice (ICJ) ruled in 1962 that the Preah Vihear Temple belonged to Cambodia, the ownership of the surrounding land remained contested. This historical tension, combined with nationalist sentiment on both sides, has fueled repeated border clashes, with the latest escalation in July 2025 becoming the most serious since 2011.

Allegations of Ceasefire Violations

Cambodia's Accusations Against Thailand: Cambodia has lodged formal complaints with the United Nations and the Association of Southeast Asian Nations (ASEAN), alleging that Thai forces have repeatedly breached the ceasefire. Key accusations include:

• Continued Military Presence: Cambodian officials claim Thai troops have not fully withdrawn from contested zones.

• Civilian Harm: Allegations have been made that Thai forces have forcibly displaced civilians, erected barbed wire in residential areas, and laid new landmines.

• Detention of Soldiers: Cambodia continues to demand the release of 18 Cambodian soldiers reportedly captured and held by Thai forces.

Thailand's Counterclaims Against Cambodia: Thailand has vehemently denied Cambodia's claims and, in turn, has accused its neighbor of its own violations. Thailand's counterarguments and allegations include:

• Aggressive Provocation: Thai military spokespersons have stated that their forces have only responded in "self-defense" to provocations initiated by Cambodian troops, including small arms fire and rocket attacks.

• Evidence of Violations: Thailand claims to have video and photo evidence of Cambodian troops laying new landmines, and has announced plans to present this evidence to the governing body of the Ottawa Treaty.

• Ongoing Hostilities: The Thai government has highlighted several specific incidents, including a mine explosion that injured three Thai soldiers, to support their claim that Cambodia is not acting in good faith.

Humanitarian and Diplomatic Impact

The recent fighting has had a devastating humanitarian toll. The five days of intense clashes in July 2025 killed at least 38 people and displaced hundreds of thousands of civilians on both sides of the border. Reports indicate that over 150,000 Cambodians and 20,000 Thais were forced to flee their homes. Displaced civilians are now living in makeshift shelters with poor sanitation and limited access to essential services. Humanitarian organizations, such as the Humanitarian Response Forum (HRF), report that the lingering fear of unexploded ordnance (UXO) is preventing many people from returning home, even after the fighting has stopped.

Diplomatic efforts are ongoing, but progress remains slow. While Malaysia, as the current ASEAN chair, brokered the initial ceasefire, the deployment of a proposed ASEAN observer team has been hindered by a lack of trust. The United Nations Secretary-General and major world powers, including the United States and China, have welcomed the ceasefire but are urging both nations to fully respect the agreement and exercise restraint. However, the continuous public accusations from both Bangkok and Phnom Penh suggest that a permanent solution is not yet in sight.

 

Cambodia Files Formal Complaint Over Thai Military's Alleged Border Encroachment

Phnom Penh, Cambodia - Amid escalating border tensions, Cambodia has lodged a formal complaint against the Thai military, accusing its forces of unilateral border encroachment. The Cambodian Joint Boundary Commission (JBC) on Land Boundary issued a protest against what it described as "unilateral land encroachment activities" by Thai troops along the shared border in Banteay Meanchey province, emphasizing that these actions are a violation of both the 2000 Memorandum of Understanding and international law.

According to a press statement from Cambodia’s State Secretariat of the Border Affairs, the JBC cited three specific incidents that occurred between August 12 and 14, 2025. In these instances, Thai soldiers allegedly moved into disputed areas to install barriers, including barbed wire, nets, and vehicle tires. The first incident was reported on August 12 in a village between Border Markers No. 46 and 47, followed by a second on August 13 near markers No. 42 and 43. The most recent incident took place on August 14 in the vicinity of the Boeung Trakoun International Border Gate. The Cambodian government noted that in this instance, Thai troops reportedly withdrew after being observed by Cambodian civilians and security forces, a move that only highlights the premeditated nature of their incursions.

The protest note demands the immediate removal of all installations and urges Thailand to take preventive measures to avoid future violations. Cambodia has also reached out to the United Nations and ASEAN, citing ongoing ceasefire breaches and the forcible displacement of Cambodian residents along the border zones.

A History of Dispute and Unresolved Boundaries

The recent complaint is the latest episode in a long-standing and complex border dispute between the two Southeast Asian neighbors. The 817-kilometer land border, much of which was drawn during French colonial rule, has remained poorly demarcated. This has led to frequent flare-ups, particularly around historical temple sites like Preah Vihear.

Cambodia's firm position is rooted in international law and a consistent commitment to peaceful resolution through legal and technical mechanisms. The Cambodian government has repeatedly stated that its actions are guided by the 1907 Franco-Siamese treaty and the 1962 ruling by the International Court of Justice (ICJ), which affirmed Cambodian sovereignty over the Preah Vihear temple. Further demonstrating its commitment to this approach, Cambodia has indicated its intention to file a new complaint with the ICJ regarding four other disputed areas: Mom Bei, Ta Moan Thom Temple, Ta Moan Tauch Temple, and Ta Krabei Temple. This strategic move aims to achieve a definitive legal resolution if bilateral talks fail.

In response to Thai accusations that it has violated the ceasefire, Cambodia’s Ministry of National Defense has maintained an "absolute and uncompromising position," stating, "we have never used, produced, or deployed new landmines under any circumstances, and we strictly and fully honour our obligations under international law."

Human Toll and Economic Impact

The escalating tensions have had a severe and immediate impact on Cambodian citizens living along the border. The conflict has displaced over 120,000 people, disrupting farming, halting business activities, and destroying crops and livestock. The loss of income has left many families in a precarious financial situation, with the National Bank of Cambodia introducing temporary debt relief measures to assist those affected.

The country's vital tourism sector has also been hit hard. Thailand was Cambodia's largest source of tourists in 2024, but ticket sales to Angkor Wat from Thai nationals plummeted by over 90 percent in July. This has had a chilling effect on the entire tourism industry, which supports approximately 510,000 direct jobs, putting the livelihoods of countless vendors, hospitality workers, and small business owners at risk. Furthermore, the situation poses a serious threat to the more than 1.2 million Cambodian migrant workers in Thailand, whose remittances are a crucial source of income for their families back home. Should diplomatic relations worsen, a large number of these workers could be forced to return, putting immense strain on Cambodia’s domestic job market.

Diplomatic and Political Context

Despite the challenges, Cambodia continues to advocate for a peaceful and diplomatic solution, with the UN Secretary-General and ASEAN urging both sides to exercise restraint. Cambodia's decision to internationalize the issue by appealing to the UN Security Council is seen as a necessary step to ensure transparency and pressure Thailand to abide by international law.

This long-standing border issue remains a significant challenge for regional stability, with international actors from Malaysia and China to the United States calling for a peaceful resolution. Cambodia's government maintains its firm commitment to dialogue, but emphasizes that any long-term solution must be based on a clear recognition of its territorial sovereignty and the full enforcement of international agreements.

 

Cambodia Files Formal Complaint Over Thai Military's Alleged Border Encroachment

PHNOM PENH — The Secretariat of the Cambodian-Thai Joint Boundary Commission (JBC), the official body responsible for border demarcation, has lodged a formal complaint with the Thai government. The complaint alleges that the Thai military has deployed barbed wire fences and other barriers, which reportedly encroach upon Cambodian villages and civilian homes. This action is viewed by Cambodia as a direct violation of its sovereignty and territorial integrity.

The complaint, which was filed through diplomatic channels, focuses on specific incidents where Thai military personnel have allegedly moved boundary markers or constructed new barriers in contested areas. The JBC is tasked with the complex and sensitive work of resolving long-standing border disputes, a process often guided by historical maps and international legal rulings, particularly those concerning key sites like the Preah Vihear temple.

According to the Cambodian government, the placement of car wheel barriers and barbed wire fences represents a unilateral and provocative act that undermines the work of the JBC and destabilizes the border region. The complaint argues that these actions not only violate the spirit of cooperation but also directly impact the lives of local residents whose land and homes are being encroached upon.

Officials from Cambodia's Ministry of Foreign Affairs have stressed the importance of resolving such issues through peaceful, diplomatic means, in accordance with established agreements. They have called on the Thai government to investigate the allegations immediately and to dismantle any barriers found to be in violation of the agreed-upon border line.

This formal complaint highlights the ongoing tensions along the shared border, where even small-scale military movements or construction can trigger significant diplomatic incidents. Both nations have previously committed to maintaining peace and stability, and the outcome of this complaint will be closely watched by regional and international observers.

Historical Context of the Dispute

The border dispute between Cambodia and Thailand has deep historical roots, largely stemming from the ambiguous French colonial mappings of the early 20th century. While the International Court of Justice (ICJ) ruled in 1962 and 2013 that the Preah Vihear temple belongs to Cambodia, the sovereignty of the surrounding territories remains a point of contention. These unresolved areas have led to periodic flare-ups in violence, with the most recent incidents causing significant displacement and casualties on both sides.

The JBC was established through a 2000 Memorandum of Understanding with the specific mandate to jointly survey and demarcate the land boundary. Its work is intended to prevent conflicts and foster a secure and prosperous frontier for people living in the border regions. However, unilateral actions such as those alleged in the complaint can undermine years of slow, painstaking progress.

Impact on Civilian Lives

The humanitarian impact of these border tensions is a primary concern for the Cambodian government. The alleged placement of barriers directly affects the livelihoods and safety of people living in these rural communities, many of whom are farmers. The barriers disrupt access to agricultural lands and can forcibly displace families from their homes. Furthermore, such actions increase the risk of accidental encounters between civilians and military personnel and raise concerns about the potential for unexploded ordnance in these areas.

Humanitarian organizations have previously reported on the severe impact of conflict in the region, citing significant numbers of displaced families and the urgent need for shelter, food, and psychological support. This latest complaint underscores the continued vulnerability of these communities to military actions that disregard diplomatic processes.

Calls for International Oversight and Diplomacy

The formal complaint has put pressure on international bodies, particularly the Association of Southeast Asian Nations (ASEAN), to play a more active role in de-escalating the situation. While ASEAN operates under a principle of non-interference, the recurring nature of these disputes and their potential to destabilize the region present a significant challenge to the bloc's credibility.

Cambodia is urging the international community to support its call for a full investigation and to condemn any actions that violate established ceasefire agreements and international law. The diplomatic outcome of this complaint will be a crucial test of whether peaceful dialogue can prevail over military provocations in one of Southeast Asia's most sensitive border regions. Both nations are expected to use upcoming bilateral meetings to address the issue, but the immediate safety of civilians remains the most pressing priority.

Analyst: Thai Military's Leadership of Observation Team Crossing into Cambodian Sovereignty is Brazen Aggression

 

Analyst: Thai Military's Leadership of Observation Team Crossing into Cambodian Sovereignty is Brazen Aggression

Introduction

Political analyst Vong Makara has condemned what he describes as the Thai military's leadership in guiding an observation team across Cambodia's sovereign borders, labeling it a "brazen act of aggression" that undermines the fragile ceasefire. This claim, echoed in recent opinion pieces and amid escalating accusations, highlights ongoing mistrust between Thailand and Cambodia following recent clashes. As observer teams from various nations monitor the border, Makara argues that such incursions violate international law and the terms of a recent border agreement. This article explores the analyst's perspective, the context of the alleged incident, and its implications for regional stability.

Background of the Border Dispute

The Thailand-Cambodia border conflict, rooted in early 20th-century French colonial mappings, spans an 800-kilometer frontier with disputed areas around the Preah Vihear and Ta Moan Thom temples. The International Court of Justice (ICJ) ruled in 1962 and 2013 that Preah Vihear belongs to Cambodia, but surrounding territories remain contested, leading to periodic violence. Tensions flared in recent months after a skirmish, escalating into full-scale clashes that killed dozens and displaced thousands before a ceasefire was brokered.

Despite the truce, mutual accusations persist. Both sides have accused the other of violating the ceasefire agreement. Thailand has alleged Cambodian aggression, such as mine-laying, while Cambodia has countered with claims of Thai use of prohibited munitions and troop incursions. These incidents have fueled claims of violations and increased mistrust.

The Alleged Incursion and Observation Team

Analyst Vong Makara, a professor and political commentator, asserts that the Thai military has been leading or influencing observation teams to cross into Cambodian sovereign areas as part of a strategy of "silent aggression." In an opinion piece, Makara describes these actions as including deploying troops to intrude and laying barbed wire within Cambodian territory—tactics designed to provoke without overt warfare. He specifically points to incidents where Thai forces accompany interim observer teams into disputed zones, framing it as a violation of Cambodia's sovereignty and a deliberate sabotage of the ceasefire.

Makara's comments align with Cambodian reports of Thai incursions, which Cambodia condemned as a breach of the ceasefire. He argues that by leading observation teams—intended to be neutral under a border agreement—Thai military personnel are engaging in "open provocations," such as fabricating claims of Cambodian aggression to justify their presence. This, Makara claims, is "brazen" because it exploits the presence of international observers to legitimize incursions, potentially escalating to renewed violence.

Thailand denies these allegations, with the Royal Thai Army stating that any border activities, including those with observer teams investigating violations, occur within Thai territory or agreed-upon zones. A Thai spokesperson emphasized that observer teams are investigating Cambodian "aggressions," and dismissed Cambodian claims as disinformation.

Violation of the Ceasefire Agreement

A recent border committee meeting resulted in an agreement that explicitly mandated the avoidance of military provocations, including unauthorized crossings and troop deployments. Makara contends that Thai-led observation team crossings violate this, as well as international law. He urges foreign military attachés and diplomatic missions to condemn these actions and support Cambodia's territorial integrity, warning that failure to do so could lead to broader regional instability.

Cambodia's Ministry of National Defence has echoed this, accusing Thailand of "brutal and illegal military aggression" and calling for UN intervention. The Cambodian Mine Action Centre (CMAC) continues surveying and clearing unexploded ordnance from the recent bombardments amid these tensions.

Broader Implications

Makara's analysis reflects Cambodian fears of Thai expansionism, fueled by historical grievances and recent events. The conflict has disrupted trade and created a humanitarian crisis with displaced workers and civilians. Social media amplifies divisions, with posts accusing both sides of aggression and propaganda.

Geopolitically, the involvement of observer teams risks entangling major powers. Analysts warn that unaddressed incursions could unravel the ceasefire, leading to renewed clashes.

Path Forward

To de-escalate, experts like Makara recommend:

• Neutral Oversight: Ensure observation teams operate independently, without military leadership from either side.

• Joint Investigations: ASEAN-led probes into alleged crossings and mine incidents.

• Ceasefire Adherence: Full implementation of the border agreement, including releasing detained soldiers.

• International Pressure: UN and ASEAN condemnation of violations to uphold sovereignty.

• Humanitarian Aid: Accelerated unexploded ordnance clearance to protect civilians.

Conclusion

Vong Makara's characterization of the Thai military's alleged leadership in observation team crossings as "brazen aggression" underscores the precarious state of the Thailand-Cambodia ceasefire. While Thailand denies the claims, the accusations highlight deep-seated mistrust and the need for transparent, neutral monitoring. Without swift international intervention, such incidents risk reigniting violence, threatening Southeast Asia's stability and cultural heritage. Both nations must prioritize dialogue over provocation to secure lasting peace.

 

Landmine Incident Wounds Three Thai Soldiers: Urgent Call for Cambodia-Thailand Ceasefire Compliance

Introduction

On the late morning of August 9, 2025, a landmine explosion in the disputed border area between Cambodia and Thailand wounded three Thai soldiers, reigniting tensions just two days after the Extraordinary General Border Committee (GBC) meeting in Kuala Lumpur, Malaysia, on August 7, 2025. The incident, reported by national and international outlets, including The Guardian and Reuters, occurred in Thailand’s Si Sa Ket province near Cambodia’s Preah Vihear province, an area fraught with historical disputes. As the fragile ceasefire, established on July 28, 2025, faces further strain, there is a pressing need for both nations to strictly implement the Agreed Minute of the GBC, particularly point 2, which calls for avoiding military provocations. This article examines the incident, the ceasefire agreement, and the urgent need for compliance to prevent further escalation and confusion at the frontlines.

The August 9 Landmine Incident

According to the Royal Thai Army, a patrol from Infantry Company 111 was conducting a routine security sweep in the Chong Don Ao-Krissana border area, approximately 1.8 kilometers from Phu Makua, when a landmine detonated around 10:00 AM on August 9, 2025. The explosion injured three soldiers: Sergeant Major First Class Thani Paha, who lost his left foot; Private Pakpoom Chaisura, who sustained arm and back injuries; and Private Thananchai Kraiwong, who suffered a concussion and ruptured eardrum. The soldiers were promptly evacuated to a local hospital for treatment. The Thai military stated that the site, within Thai territory, had been cleared of mines earlier, suggesting the device was recently planted.

Thailand’s Ministry of Foreign Affairs accused Cambodia of laying the landmine, labeling it a “blatant violation” of the 1997 Ottawa Convention banning anti-personnel mines, to which both countries are signatories. Major General Winthai Suvaree, Thai army spokesperson, called the incident “a significant obstacle to ceasefire measures and peaceful resolution,” as reported by PBS News and Al Jazeera. Cambodia’s Ministry of National Defence responded cautiously, stating it “has yet to receive clear confirmation from frontline forces” but affirmed its commitment to the ceasefire. The Cambodian Mine Action and Victim Assistance Authority (CMAA) denied planting new mines, suggesting the device could be a remnant from past conflicts, given Cambodia’s estimated 4–6 million unexploded ordnance (UXO) from decades of war.

Context of the Border Conflict

The Thailand-Cambodia border dispute, rooted in colonial-era mappings by French authorities, centers on contested areas along the 800-kilometer frontier, particularly near the Preah Vihear and Ta Moan Thom temples. The International Court of Justice (ICJ) rulings in 1962 and 2013 awarded Preah Vihear to Cambodia, but surrounding territories remain disputed, fueling periodic clashes. The latest escalation began in May 2025 with a Cambodian soldier’s death, followed by landmine incidents on July 16 and 23 wounding Thai soldiers. By late July, heavy fighting, including Cambodian rocket attacks and Thai airstrikes, killed at least 43 people and displaced over 260,000, prompting a Malaysia-brokered ceasefire on July 28, 2025, supported by U.S. tariff pressure and ASEAN mediation.

Despite the ceasefire, tensions persist. Thailand’s detention of 18 Cambodian soldiers since July 29, 2025, and allegations of Cambodian PMN-2 landmine planting, countered by Cambodia’s claims of Thai cluster munition use, have strained relations. The August 9 incident, the fourth landmine-related injury to Thai soldiers in recent weeks, underscores the ceasefire’s fragility and the risk of further “confused situations” at the frontlines.

The Extraordinary General Border Committee Meeting

The Extraordinary GBC meeting, held on August 7, 2025, in Kuala Lumpur, Malaysia, was a critical step toward stabilizing the ceasefire. Hosted by Malaysian Prime Minister Anwar Ibrahim, the meeting resulted in a 13-point Agreed Minute, formalizing commitments to de-escalate tensions. Point 2, as highlighted by Cambodia’s Ministry of National Defence, specifically mandates “avoiding military provocations” by both sides, including halting troop movements, refraining from hostile actions, and ensuring compliance with agreed patrol routes. The agreement also allowed ASEAN observers to monitor disputed areas, a measure aimed at preventing incidents like the August 9 landmine explosion.

Both nations expressed gratitude to Malaysia, with Cambodian Prime Minister Hun Manet nominating U.S. President Donald Trump for a Nobel Peace Prize for his role in pressuring the ceasefire. However, the August 9 incident, occurring just 48 hours later, highlights the challenges of implementing the Agreed Minute, particularly point 2, which seeks to prevent actions that could be perceived as provocative or escalatory.

Cambodia’s Call for Compliance

Cambodia has urged Thailand to strictly adhere to the GBC’s Agreed Minute to avoid further incidents and misunderstandings. CMAA Senior Minister Ly Thuch emphasized that Cambodia has complied with the ceasefire, including respecting agreed patrol routes and refraining from deploying new mines. Posts on X, such as by @pheaktraneth on August 9, 2025, reflect Cambodian sentiment, rejecting Thailand’s accusations and calling for joint investigations into UXO origins. Cambodia argues that the region’s legacy of millions of UXO from past wars, including the Khmer Rouge era, complicates attribution, and insists that only cooperative efforts can clarify responsibility.

Thailand, however, maintains that the landmine was a newly planted PMN-2, citing its August 20 discovery of a smartphone in Phu Makhuea allegedly showing Cambodian soldiers handling such mines. Cambodia dismissed this as inconclusive, noting that the mines displayed to international observers on August 16 had intact arming pins, rendering them non-functional. This back-and-forth underscores the need for both sides to honor point 2 of the Agreed Minute to prevent miscalculations and ensure transparency.

Humanitarian and Regional Implications

The August 9 incident exacerbates the humanitarian crisis in the border region. The wounded soldiers highlight the ongoing danger of UXO, which threatens returning civilians in Si Sa Ket, Surin, and Oddar Meanchey provinces. CMAC has intensified efforts to survey, mark, and clear UXO, including MK-84 bombs and M-46 cluster sub-munitions from Thai artillery, as verified by a 14-nation defense attaché delegation on August 10, 2025, in Thordaun Village. These remnants, scattered across farmland and villages, pose long-term risks, with CMAC urging residents to report sightings to its hotline (023-880-489).

The incident also risks derailing the ceasefire. Thailand’s threat to exercise “self-defense” under international law, as stated on August 12, 2025, and Cambodia’s accusations of Thai cluster munition use violating humanitarian principles, deepen mistrust. The economic toll is significant, with 780,000 Cambodian migrant workers returning from Thailand and trade disrupted. Social media on X, including posts by @armyspoke_news and @MinistryofInfo1, reflects polarized narratives, with Thailand accusing Cambodia of disinformation and Cambodia calling for international oversight.

Path to Stability

To prevent further incidents and confusion, both nations must:

1. Implement Point 2: Strictly adhere to the GBC’s commitment to avoid military provocations, ensuring patrols stay within agreed routes and no new ordnance is deployed.

2. Joint Investigations: Establish an ASEAN-led team to verify the origin of the August 9 landmine, addressing disputes over PMN-2 mines and UXO.

3. UXO Clearance: Thailand and Cambodia should collaborate on mine clearance, with international support from Japan and Norway, to protect civilians.

4. Release Detainees: Thailand’s release of the 18 Cambodian soldiers could rebuild trust and support ceasefire compliance.

5. Protect Cultural Sites: Both sides must safeguard Prasat Preah Vihear, damaged by artillery, per the 1954 Hague Convention.

The upcoming GBC meeting in Siem Reap (September 8–10, 2025) offers a critical opportunity to reinforce these commitments and address the August 9 incident.

Conclusion

The landmine explosion on August 9, 2025, wounding three Thai soldiers, underscores the fragility of the Thailand-Cambodia ceasefire and the urgent need to implement the Agreed Minute of the August 7 GBC meeting, particularly point 2 on avoiding military provocations. As of August 20, 2025, mutual accusations over the landmine’s origin and ongoing tensions, including Thailand’s detention of Cambodian soldiers, threaten to destabilize the truce. Collaborative investigations, UXO clearance, and adherence to international law are essential to prevent further incidents and confusion at the frontlines. The international community, through ASEAN and the UN, must support these efforts to ensure lasting peace and safety for communities along the Cambodia-Thailand border.
