Cambodia Security Report — July 12, 2026

Security analysis based on open-source intelligence and web research. Period: July 05 — July 12, 2026.

Executive Summary

Cambodia's security landscape from July 5 to July 12, 2026, was characterized by a complex interplay of warming diplomatic ties with the United States, deepening strategic cooperation with China, and persistent border tensions with Thailand. Diplomatic efforts saw Cambodia and the US reaffirming stronger bilateral relations, including the planned resumption of joint military exercises and increased trade. Concurrently, Cambodia continued to solidify its comprehensive strategic partnership with China, with Prime Minister Hun Manet slated for a visit to Beijing to further enhance cooperation across various sectors, including defense. A significant concern remained the volatile border with Thailand, where Cambodia lodged formal protests against alleged Thai military incursions and fortifications in Oddar Meanchey province. Furthermore, Cambodia is moving forward with mandatory military conscription from 2026 and has initiated a UN-backed conciliation process to resolve a long-standing maritime dispute with Thailand, while also continuing its crackdown on cybercrime, albeit with reports of ongoing abuses.

Key Security Developments

• Warming Cambodia-US Diplomatic and Defense Relations
  Cambodia and the United States reaffirmed their commitment to deepening bilateral relations during talks between Deputy Prime Minister and Foreign Minister Prak Sokhonn and US Chargé d'Affaires ad interim Aleksandra Zittle on July 10, 2026, in Phnom Penh. Discussions covered expanding cooperation in trade, investment, defense, security, and combating transnational crime. The US also confirmed it is closely monitoring tensions along the Cambodia-Thailand border and supports peaceful dispute resolution. This follows a period of strategic normalization, including the US lifting Cambodia from its arms sale blacklist in early 2026 and the finalization of plans to resume annual joint military exercises, "Angkor Sentinel," in late 2026 or early 2027 after a nine-year pause.

• Deepening Cambodia-China Strategic Partnership
  Prime Minister Hun Manet is scheduled to visit China in mid-July 2026 to further deepen bilateral cooperation, following a goodwill visit by Senate President Hun Sen to Beijing in late June. This visit aims to implement directions agreed upon by top leaders, focusing on economy, investment, trade, infrastructure, agriculture, technology, and people-to-people exchanges. China has also expressed willingness to establish a formal security partnership with Cambodia and enhance cooperation through the "2+2 Strategic Dialogue Mechanism," with an emphasis on defense coordination, intelligence sharing, and joint action against cross-border crime.

• Ongoing Border Tensions with Thailand
  Cambodia lodged a formal protest against Thailand between July 5 and July 9, 2026, citing continued violations of its sovereignty by Thai military forces along the frontier in Oddar Meanchey province. The Ministry of Foreign Affairs reported Thai troops carried out earthworks and installed barbed-wire near Boundary Pillars No. 14 and No. 22, actions Cambodia considers a clear violation of its territorial integrity and a breach of the December 2025 ceasefire commitments. Cambodia has urged Thailand to cease these activities and resume border talks to de-escalate tensions.

• Enforcement of Mandatory Military Conscription
  Cambodia announced it will begin enforcing its long-dormant Law on Compulsory Military Service from 2026, requiring men aged 18-30 to serve for 18 months, with plans to extend this to 24 months. Prime Minister Hun Manet stated this move aims to address shortages in junior ranks and ensure a ready military force, partly in response to rising border tensions with Thailand.

• Initiation of UNCLOS Conciliation for Maritime Dispute with Thailand
  Cambodia formally informed the United Nations and Thailand on June 2, 2026 (relevant to the current period as an ongoing diplomatic process), of its initiation of a compulsory conciliation process under the UN Convention on the Law of the Sea (UNCLOS) to resolve a long-running maritime boundary dispute. This action follows Thailand's unilateral termination of a 2001 agreement that provided a framework for talks over the disputed Overlapping Claims Area (OCA) in the Gulf of Thailand, which is rich in energy resources.

• Defense Cooperation with Malaysia
  On July 9, 2026, Commander-in-Chief of the Royal Cambodian Armed Forces, Vong Pisen, urged Malaysian Armed Forces Chief General Tan Sri Malek Razak Sulaiman to fast-track the signing of a memorandum of understanding on national defense and expand military collaboration. The proposed cooperation includes increased training, joint exercises, information sharing, and efforts to prevent cross-border crimes. Malaysia expressed support for strengthening military ties and continuing its role in the ASEAN Observer Team (AOT) for the Cambodia-Thailand border dispute.

• Continued Crackdown on Cybercrime and Human Trafficking
  Cambodia continues its efforts to dismantle online scam centers, with a new Law on Anti-Technology Fraud passed in April 2026, introducing severe penalties for organized fraud, human trafficking, and cryptocurrency-based money laundering. However, a June 8, 2026, report by Amnesty International indicated that widespread abuses persist in these compounds, and the crackdown has largely failed to dismantle most operations, with many trafficking victims not receiving adequate protection. Authorities conducted inspections in Phnom Penh, Svay Rieng, Preah Sihanouk, and Banteay Meanchey provinces in early June, targeting suspected scam locations.

• Resumption of Joint Military Exercises with the US (Angkor Sentinel)
  After a nearly decade-long suspension, Cambodia and the United States will resume the "Angkor Sentinel" joint military exercise in late 2026 or early 2027. This revival of bilateral defense cooperation follows the US lifting its arms embargo on Cambodia and is aimed at deepening military cooperation and strengthening bilateral ties, with a focus on interoperability, professional training, and crisis response.

• Ongoing Joint Military Exercises with China (Golden Dragon)
  Preparations are underway for the "Golden Dragon 2026" joint military exercise between Cambodia and China, which focuses on counter-terrorism, humanitarian relief, and disaster response. These annual drills, held since 2016, have expanded to include ground, naval, and air forces, and are seen as a symbol of the deepening military cooperation and strategic ties between the two nations.

Geopolitical Impact and Regional Dynamics

Cambodia's recent security developments highlight its delicate and increasingly complex balancing act between major global powers, primarily the United States and China. The warming of Cambodia-US relations, marked by the resumption of military exercises and increased economic cooperation, signals a strategic diversification aimed at ensuring economic legitimacy and avoiding excessive dependence on any single power. This "multi-geared hedging" strategy allows Phnom Penh to engage with Washington on trade and security while simultaneously deepening its comprehensive strategic partnership with Beijing, which remains a crucial source of infrastructure capital and diplomatic support. This dual engagement, however, places Cambodia in a precarious position amidst intensifying Sino-American rivalry in the Indo-Pacific.

The persistent border tensions with Thailand, including recent alleged incursions and fortifications, pose a significant challenge to regional stability. Cambodia's formal protests and initiation of UNCLOS conciliation for the maritime dispute underscore its commitment to resolving issues through international law, yet the ongoing incidents risk further escalation. The US has expressed concern and called for peaceful resolution, indicating a broader regional interest in de-escalation. The involvement of Malaysia in mediating the 2025 border dispute and its continued support for the ASEAN Observer Team (AOT) also highlights the regional dimension of this conflict and ASEAN's role in maintaining stability.

The enforcement of mandatory military conscription, partly attributed to the Thai border tensions, reflects Cambodia's internal efforts to bolster its defense capabilities and modernize its armed forces. This move, alongside continued joint exercises with both China and the US, demonstrates Cambodia's intent to enhance its military readiness and interoperability with diverse partners. However, the deepening military ties with China, particularly around facilities like Ream Naval Base, continue to raise concerns among some Southeast Asian nations and Western observers regarding Beijing's expanding military footprint and its implications for regional maritime security.

Military and Defense Analysis

Cambodia is actively pursuing a strategy to enhance its military capabilities and readiness, driven by both internal modernization goals and external security challenges, particularly along its border with Thailand. The decision to enforce mandatory military conscription from 2026, with an intended extension of service from 18 to 24 months, is a significant step to address personnel shortages and strengthen the Royal Cambodian Armed Forces (RCAF). This move is explicitly linked to the need for a ready military force amidst rising border tensions.

In terms of modernization programs and defense spending, Prime Minister Hun Manet has pledged to "look at increasing" Cambodia's defense budget, which stood at $725 million in 2025, to accelerate the army's modernization. The country is also expanding its defense partnerships and acquiring new assets. The resumption of the "Angkor Sentinel" joint military exercise with the United States in late 2026 or early 2027, after a nine-year hiatus, is aimed at enhancing interoperability, professional training, and crisis-response capacity through Western standards. Simultaneously, Cambodia continues to conduct the "Golden Dragon" joint military exercises with China, which have expanded to include ground, naval, and air forces, focusing on counter-terrorism and disaster relief. These dual engagements reflect a strategy of "active neutrality" to diversify security dependencies. The recent call for Malaysia to fast-track a defense MoU and expand military collaboration further underscores Cambodia's efforts to broaden its defense cooperation network within ASEAN.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Cambodia is likely to continue its diplomatic offensive regarding the border dispute with Thailand, pushing for the resumption of Joint Boundary Commission (JBC) talks and emphasizing peaceful resolution under international law. The US will likely maintain its monitoring role and encourage dialogue. Prime Minister Hun Manet's planned visit to China in mid-July will further solidify economic and security ties, potentially leading to new agreements or initiatives. Domestically, preparations for the implementation of mandatory military conscription will intensify, with public awareness campaigns and logistical arrangements being key. The crackdown on cybercrime is expected to continue, but the effectiveness in dismantling major operations and protecting victims will remain under scrutiny, especially following critical reports from human rights organizations.

Critical flashpoints and risk areas: The Cambodia-Thailand land border, particularly in Oddar Meanchey province, remains a critical flashpoint. Any further alleged incursions or military fortifications by either side could quickly escalate tensions, potentially leading to renewed armed clashes despite the existing ceasefire. The Overlapping Claims Area (OCA) in the Gulf of Thailand is another significant risk area. While Cambodia has initiated a UNCLOS conciliation process, Thailand's unilateral termination of the 2001 agreement and the high economic stakes (oil and gas reserves) could lead to increased maritime posturing or incidents. The effectiveness and transparency of the cybercrime crackdown are also critical. Failure to genuinely dismantle scam networks and protect victims could lead to continued international criticism and potential sanctions, impacting Cambodia's international standing and economy.

Indicators to monitor: Key indicators to monitor include the progress of the UNCLOS conciliation process with Thailand and any responses from Bangkok. On the land border, observe reports of military movements, construction activities, or diplomatic protests. The outcomes and specific agreements from Prime Minister Hun Manet's visit to China will be crucial for understanding the trajectory of Cambodia-China relations. Domestically, monitor public sentiment and implementation challenges related to military conscription. Internationally, watch for further reports from human rights organizations on cybercrime compounds and any reactions or policy adjustments from the Cambodian government. The scheduling and scope of the "Angkor Sentinel" exercises with the US and "Golden Dragon" exercises with China will also provide insights into Cambodia's defense posture and strategic alignments.

Strategic recommendations: Cambodia should prioritize de-escalation and diplomatic engagement with Thailand to prevent further border clashes, leveraging regional mechanisms like ASEAN and the ASEAN Observer Team (AOT). It should ensure full transparency and adherence to international law in the UNCLOS conciliation process for the maritime dispute. To address the cybercrime issue, Cambodia needs to move beyond superficial crackdowns to dismantle the underlying criminal networks, enhance victim protection, and collaborate more effectively with international law enforcement agencies, addressing concerns raised by human rights organizations. While balancing relations with both the US and China, Cambodia should ensure its defense cooperation agreements contribute to its national security interests without compromising its sovereignty or regional stability. The implementation of military conscription should be managed transparently and fairly to maintain public support and ensure effective force generation.
