This 14-day exercise focused on enhancing interoperability through joint coordination in planning and executing tactical operations in a sub-conventional, semi-urban environment, including sniper training, mortar drills, and tactical drone employment. The exercise strengthened bilateral military relations and fostered mutual understanding.

• Cambodian Army Participates in Multinational Exercise PRAGATI 2026 in India

This two-week exercise involves armed forces from 12 friendly nations and is designed to enhance operational coordination, build mutual trust, and strengthen joint capabilities, with a specific focus on counter-terrorism operations in semi-mountainous and forested terrains.

• Intensified Crackdown on Cross-Border Online Scam Networks
  The Cambodian government pledged to intensify its ongoing crackdowns on transnational crime and online scam networks, asserting that the kingdom will no longer serve as a safe haven for international criminal syndicates. On May 17, 2026, two South Koreans were rescued after being held in scam-related captivity in Cambodia. This follows significant efforts, including investigations into over 250 online scam locations and the shutdown of 91 casinos between July 2025 and mid-April 2026.

• Laos and Cambodia Join Forces Against Cross-Border Scams
  On May 14, 2026, Lao Minister of Public Security, Lieutenant General Vanthong Kongmany, met with Cambodian Minister of Interior, Sar Sokha, to strengthen cooperation against online scam operations and other cross-border crimes. They agreed to enhance information-sharing and collaboration between law enforcement agencies to prevent and suppress criminal activities along their shared border.

• Cybersecurity Day 2026 Focuses on Financial Sector Resilience
  On May 20, 2026, Cybersecurity Day 2026 was held in Phnom Penh under the theme "Strengthening Cybersecurity Resilience in Cambodia's Banking and Financial Sector." Organized by the Association of Banks in Cambodia (ABC), the event brought together over 500 participants to address the increasing exposure to risks of system disruption, cyberattacks, fraud, and data breaches in the rapidly digitalizing financial sector.

• Cambodia Welcomes Thai Initiative for Border Talks
  On May 23, 2026, Cambodia's Deputy Prime Minister and Minister of National Defence, General Tea Seiha, welcomed Thailand's initiative to hold bilateral border meetings through existing mechanisms, including talks between the defense ministers. This response followed Thailand's Defense Minister, Lieutenant General Adul Boonthamcharoen's, statement of readiness to move forward with bilateral border mechanisms to ease tensions.

• Diplomatic Briefing on Cambodia-Thailand Border Cultural Heritage
  On May 23, 2026, Cambodia's Ministry of Foreign Affairs and International Cooperation hosted a diplomatic briefing on the situation surrounding Cambodian cultural sites along the Cambodia–Thailand border. Minister of Culture and Fine Arts, Phoeurng Sackona, reaffirmed Cambodia's legal basis for sovereignty over cultural sites occupied by Thai armed forces since December 2025 and reiterated commitment to peaceful resolution in accordance with international law.

• Reaffirmation of Peaceful Approach to Cambodia-Thailand Border Issues
  On May 21, 2026, the Royal Government of Cambodia reaffirmed its firm commitment to resolving border issues with Thailand through peaceful means, respect for international law, and existing bilateral agreements. Cambodia strongly rejected any attempt to alter the border through the use of force and emphasized the continued use of the Joint Boundary Commission mechanism.

• Vietnam and Cambodia Reaffirm Strong Defense-Security Ties
  On May 21, 2026, Vietnamese Minister of Foreign Affairs Lê Hoài Trung hosted a reception for the newly-appointed Cambodian Ambassador to Vietnam, Touch Sopharath. Both sides reaffirmed their commitment to strengthening political trust, maintaining regular high-level exchanges, and enhancing national defense-security ties, as well as coordinating responses to non-traditional security challenges.

• US-Cambodia Discussions on Border Peace and Stronger Ties
  On May 12, 2026, Deputy Prime Minister and Foreign Minister Prak Sokhonn held a telephone conversation with Allison Hooker, U.S. Under Secretary of State for Political Affairs. Both sides welcomed positive momentum in relations and discussed ways to deepen cooperation in defense, security, and combating transnational crime, with the US expressing support for peaceful efforts to resolve the Cambodia–Thailand border dispute.

• Implementation of Military Conscription in 2026
  Cambodia is set to implement military conscription starting in 2026, a decision linked to persistent border tensions with Thailand and the goal of upgrading the military's capabilities. Prime Minister Hun Manet emphasized on May 12, 2026, that national defense is crucial and "peace cannot be requested from anyone," with the National Assembly unanimously passing the Military Service Law. The updated draft law reduces the upper age limit for mandatory service to 25 and extends the service period to 24 months.

Geopolitical Impact and Regional Dynamics

Cambodia's security developments during this period underscore its strategic positioning within Southeast Asia, navigating complex relationships with major global powers and its immediate neighbors. The ongoing border tensions with Thailand, despite diplomatic efforts, remain a significant regional flashpoint. Cambodia's proactive engagement in bilateral talks and its reaffirmation of peaceful, law-based approaches are crucial for regional stability, as highlighted by a former diplomat who warned against maritime confrontation undermining ASEAN's identity. The involvement of the US in supporting the Cambodia-Thailand peace process and China's role in urging better relations demonstrate the broader international interest in de-escalating this particular dispute.

The deepening strategic partnership with China is a defining feature of Cambodia's geopolitical alignment. The recent upgrade of the "2+2" strategic dialogue to a "3+3" mechanism, involving public security ministries, signifies a comprehensive and institutionalized cooperation across defense, foreign policy, and internal security. This robust relationship, characterized by China's extensive economic, military, and political support, positions Cambodia as a close ally of China within ASEAN. This alignment, however, continues to be a point of concern for the United States, particularly regarding China's military presence at Ream Naval Base.

Cambodia's active participation in multinational military exercises like PRAGATI 2026 with India and other ASEAN nations, alongside its bilateral exercise CINBAX-II 2026 with India, indicates a strategy of diversifying defense partnerships and enhancing interoperability beyond its primary relationship with China. These exercises, focusing on counter-terrorism, contribute to regional security cooperation and signal Cambodia's commitment to addressing shared non-traditional security threats. The strong and stable defense-security ties reaffirmed with Vietnam also contribute to a complex web of regional alliances and cooperation, balancing against potential over-reliance on any single power.

Military and Defense Analysis

Cambodia's military and defense posture is undergoing significant modernization, driven by both internal security concerns and persistent border disputes. The decision to implement mandatory military conscription starting in 2026, with a service period of 24 months for citizens aged 18 to 25, marks a pivotal shift in defense policy. Prime Minister Hun Manet explicitly linked this move to persistent border tensions with Thailand and the need to upgrade military capabilities, emphasizing that national defense cannot be outsourced. This initiative aims to address shortages and professionalize the armed forces, moving towards a "duty-based on need" system.

The Royal Cambodian Armed Forces (RCAF) are actively engaged in enhancing their capabilities through international cooperation. The conclusion of CINBAX-II 2026 with India on May 16, 2026, provided valuable training in counter-terrorism operations, tactical drone employment, and urban warfare, directly improving the army's operational responses in complex scenarios. Furthermore, Cambodia's participation in the multinational PRAGATI 2026 exercise in India, starting May 20, 2026, reinforces its commitment to regional counter-terrorism efforts and interoperability with a broader range of partners.

While specific defense spending trends for the reporting period are not available, Prime Minister Hun Manet has previously pledged to "look at increasing" Cambodia's defense budget in conjunction with the conscription implementation. China remains a crucial partner in Cambodia's defense modernization, having provided significant military equipment and assisted in upgrades to facilities like the Ream Naval Base. The US, while acknowledging Cambodia's sovereignty in choosing partners, continues to encourage transparency regarding China's activities at Ream Naval Base and seeks to streamline and enhance defense trade with Cambodia. These developments indicate a strategic effort by Cambodia to build a more robust and self-reliant defense force, while carefully balancing its relationships with major powers.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Cambodia is likely to continue its dual-track approach of diplomatic engagement and internal security strengthening. The proposed bilateral border talks with Thailand, including at the defense minister level, are a positive indicator for de-escalation, and progress on these discussions will be closely watched. The crackdown on online scam networks will intensify, with continued arrests and closures of scam compounds, potentially leading to more international cooperation with countries like Laos and South Korea. The implementation of military conscription will begin to take shape, with initial recruitment and training phases. Cybersecurity initiatives, particularly in the financial sector, will see further development following Cybersecurity Day 2026.

Critical flashpoints and risk areas: The Cambodia-Thailand border remains a critical flashpoint. Despite diplomatic efforts, historical tensions and unresolved territorial claims, particularly around cultural heritage sites, could lead to renewed localized skirmishes or increased military posturing. The potential for civilian encroachment and military displays, as reported by Thailand, could trigger misunderstandings. The effectiveness of the ongoing crackdown on online scam operations and human trafficking is another risk area; failure to completely dismantle these networks could continue to damage Cambodia's international reputation and invite further sanctions or pressure from countries like the US. The Ream Naval Base and the extent of China's military presence there will remain a sensitive geopolitical issue, potentially impacting Cambodia's relations with the US and other regional actors.

Indicators to monitor: Key indicators to monitor include the frequency and outcomes of bilateral meetings between Cambodia and Thailand regarding border demarcation and de-escalation. The number of successful raids and arrests related to online scam operations, along with the repatriation of victims, will indicate the effectiveness of Cambodia's anti-scam efforts. Any new defense acquisitions or significant military exercises with either China or the US would signal shifts in Cambodia's strategic alignments. Statements from ASEAN, particularly concerning regional stability and dispute resolution mechanisms, will also be important. Furthermore, monitoring the progress of military conscription implementation and public reaction to it will provide insights into internal stability.

Strategic recommendations: Cambodia should prioritize sustained, transparent dialogue with Thailand to achieve a lasting resolution to border disputes, potentially leveraging ASEAN's mediation capabilities. Continued robust enforcement against online scam networks, coupled with international intelligence sharing and victim support, is essential to restore international trust and combat human trafficking. While maintaining its strong relationship with China, Cambodia should also actively pursue a diversified defense and diplomatic strategy, engaging with a broader range of partners like India, the US, and ASEAN members to enhance its strategic autonomy and resilience. Investing in cybersecurity infrastructure and public awareness campaigns will be crucial to protect its digital economy and citizens from evolving cyber threats.
