Laos Security Report — September 20, 2026

Security analysis based on open-source intelligence and web research. Period: September 13 — September 20, 2026.

Executive Summary

Laos experienced a period of heightened diplomatic and military engagement from September 13 to September 20, 2026, primarily strengthening ties with China, Vietnam, and Thailand. Key developments include a joint humanitarian military exercise with China in Vientiane, ongoing efforts to combat cross-border crime with Vietnam and Thailand, and the hosting of a major international conference on cluster munitions. Despite these cooperative efforts, the country continues to grapple with the pervasive threat of unexploded ordnance (UXO) and localized civil unrest in Xaisomboun Province. These dynamics underscore Laos's strategic balancing act between leveraging regional partnerships for security and development, while addressing persistent internal and transnational security challenges.

Key Security Developments

• Joint Military Exercise with China: "Peace Train-2026"
  The Chinese and Lao militaries are conducting their sixth joint humanitarian assistance and medical services exercise, "Peace Train-2026," in Vientiane. The exercise, which began on September 7, 2026, and is scheduled to run through late September, involves over 700 personnel from both sides. This initiative aims to enhance capabilities in joint rescue, natural disaster response, and medical support, further deepening military cooperation between the two nations.

• High-Level Defense Talks with China
  On September 14, 2026, Chinese Defense Minister Dong Jun held talks with visiting Lao Deputy Prime Minister and Minister of National Defense Khamlieng Outhakaysone in Beijing. The discussions focused on strengthening high-level exchanges and enhancing practical cooperation to build an "all-weather China-Laos community with a shared future" and safeguard regional stability. This meeting coincided with the 65th anniversary of diplomatic relations between China and Laos, designated as the "Laos-China Friendship Year."

• Laos Welcomes Deeper Defense Ties with China
  Lao Deputy Prime Minister and Minister of National Defense Khamlieng Outhakaysone, speaking at the Beijing Xiangshan Forum on September 18, 2026, welcomed closer defense ties with China. He highlighted that this cooperation is instrumental in maintaining peace and stability along their shared border and acknowledged the significant annual support from the Chinese People's Liberation Army for the training and capacity-building of Lao People's Army personnel.

• Third Review Conference of the Convention on Cluster Munitions
  Laos hosted the Third Review Conference of the Convention on Cluster Munitions (CCM) in Vientiane from September 14-18, 2026, with over 500 delegates from more than 120 countries and international organizations attending. On September 13, delegates inspected an unexploded ordnance (UXO) clearance site in Phikyai village, Luang Prabang, to gain first-hand insight into Laos's ongoing UXO challenge.

• Persistent Threat of Unexploded Ordnance (UXO)
  A senior Lao official warned on September 17, 2026, that an estimated 80 million unexploded munitions remain buried across Laos. Cuts in international funding could impede clearance work, prolonging the threat to civilian lives. In 2026, UXO clearance teams reached over 1.1 million people with safety messages, and the government is developing an Explosive Ordnance Risk Education (EORE) strategy for 2027-2030.

• Enhanced Cross-Border Drug Trafficking Control with Vietnam
  Laos and Vietnam beefed up control of cross-border drug trafficking, as reported on September 18, 2026. A joint exercise was conducted to strengthen coordination in preventing, suppressing, and responding to cross-border security threats, with a particular focus on intercepting armed drug traffickers. This highlights continued cooperation in maintaining stability along their shared border.

• Border Security and Cybercrime Cooperation with Thailand
  The 30th Thailand-Laos General Border Committee (GBC) meeting, co-chaired by the defense ministers, took place on September 9, 2026, in Vientiane. Both sides agreed to intensify cooperation on narcotics trafficking, regulate vessels on the Mekong River to counter illicit goods smuggling, address transboundary forest fires and haze, and combat technology-related crime. This follows a September 2, 2026, handover of 34 Thai nationals linked to cybercrime and online gambling operations to Thai officials.

• Participation in China-ASEAN Expo
  Laos participated in the 23rd China-ASEAN Expo (CAEXPO) and China-ASEAN Business and Investment Summit in Nanning, China, from September 17-21, 2026. Deputy Prime Minister Saleumxay Kommasith highlighted the expanding economic ties between ASEAN and China, with China remaining ASEAN's largest trading partner. Laos used the platform to promote its products, tourism, and investment opportunities, particularly for Sekong Province as this year's "City of Charm."

• U.S.-Laos Comprehensive Partnership Discussion
  On September 18, 2026, a CSIS event discussed "A Decade of U.S.-Laos Comprehensive Partnership," covering diplomatic and economic ties, war legacies, rare earth mining, and the future of the Mekong River. This year marks the 10th anniversary of the partnership, indicating ongoing, albeit less prominent in this reporting period, engagement with the United States.

• Civil Unrest in Xaisomboun Province
  A U.S. Travel Advisory, updated July 28, 2026, advises reconsidering travel to Xaisomboun Province due to civil unrest, noting a continued threat of violence. The U.S. government has limited ability to provide emergency services in this province.

Geopolitical Impact and Regional Dynamics

Laos's security posture during this period is largely defined by its deepening engagement with its immediate neighbors and major regional powers, particularly China. The "Peace Train-2026" joint military exercise with China, focusing on humanitarian assistance, not only enhances Laos's disaster response capabilities but also publicly demonstrates the robust and growing defense cooperation between Vientiane and Beijing. This aligns with China's broader Belt and Road Initiative and its efforts to build a "community with a shared future" in the region, positioning Laos as a key partner in mainland Southeast Asia. The high-level defense talks in Beijing further solidify this strategic alignment, emphasizing mutual support and regional stability.

Simultaneously, Laos maintains strong security and diplomatic ties with Vietnam and Thailand. The intensified cooperation with Vietnam on cross-border drug trafficking and border management underscores the enduring "special solidarity" between the two socialist nations, which is a cornerstone of Laos's security architecture, as highlighted by the 1977 Treaty of Amity and Cooperation. Similarly, the General Border Committee meeting with Thailand addresses shared transnational crime concerns, including narcotics and cybercrime, and aims to ensure stability along the Mekong River. These bilateral efforts are crucial for managing porous borders and mitigating regional security threats that transcend national boundaries.

The hosting of the Third Review Conference of the Convention on Cluster Munitions in Vientiane from September 14-18, 2026, elevates Laos's role in international humanitarian diplomacy. As the most heavily bombed country per capita, Laos uses this platform to advocate for global action against UXO, transitioning from a "victim country" to a leader in disarmament efforts. This initiative garners international attention and support, reinforcing Laos's commitment to peace and humanitarian action, even as major powers like the US, China, and Russia have not signed the convention. While the U.S.-Laos Comprehensive Partnership marks its 10th anniversary, the direct security engagement with the U.S. appears less prominent in this period compared to that with China and its immediate neighbors, focusing more on economic ties and war legacies.

Military and Defense Analysis

Laos's military, the Lao People's Army, remains relatively small with 29,100 active personnel and an estimated defense budget of $23 million in 2026, representing approximately 0.2% of its GDP. This low expenditure necessitates a significant reliance on foreign assistance for modernization, infrastructure, and training. The country's defense policy is anchored in its long-standing relationship with Vietnam, formalized by the 1977 Treaty of Amity and Cooperation, which includes regular high-level exchanges and integrated defense cooperation plans.

The recent "Peace Train-2026" joint exercise with China in Vientiane highlights a growing trend of military cooperation with Beijing, particularly in humanitarian assistance and medical services. This collaboration provides the Lao military with valuable training and equipment, enhancing its capabilities in disaster response and medical support. The Lao Deputy Prime Minister and Minister of National Defense explicitly acknowledged China's "significant annual support for the training and capacity-building of Lao People's Army personnel," indicating a reliance on Chinese expertise and resources for force modernization.

While specific defense acquisitions were not reported in this period, the overall trend suggests continued dependence on Vietnamese military advisors and Russian technical support for maintaining a functional deterrent. The military's focus appears to be on internal security, border management, and humanitarian operations, rather than large-scale conventional warfare capabilities. The cooperation with Thailand and Vietnam on border security and combating transnational crime further underscores this operational focus, aiming to enhance the military's ability to address non-traditional security threats.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Laos will likely continue to deepen its military and diplomatic engagements with China, Vietnam, and Thailand. The "Peace Train-2026" exercise with China is set to conclude by late September, and its outcomes will likely be highlighted as a success in bilateral cooperation. The momentum from the 30th Thailand-Laos General Border Committee meeting and ongoing cooperation with Vietnam suggests continued joint operations and information sharing to combat cross-border crime, particularly drug trafficking and cybercrime. The focus on UXO clearance and victim assistance will remain a national priority, especially following the Third Review Conference of the Convention on Cluster Munitions, with efforts to implement the Vientiane Action Plan for 2027-2032.

Critical flashpoints and risk areas: The primary internal flashpoint remains Xaisomboun Province, where civil unrest poses a continued threat of violence. This situation could escalate or spread, impacting internal stability. Along the Laos-Burma border, the presence of bandits, drug traffickers, and armed groups against the Burmese government presents a persistent security risk, potentially leading to cross-border incursions or increased criminal activity. The vast number of remaining unexploded ordnance (UXO) across the country, particularly in provinces like Luang Prabang, Savannakhet, and Xieng Khouang, continues to pose a daily threat to civilian lives and livelihoods, with potential funding cuts exacerbating the problem.

Indicators to monitor: Key indicators to monitor include the frequency and scale of joint military exercises with China and Vietnam, any new defense cooperation agreements or acquisitions, and the effectiveness of cross-border crime suppression efforts with Thailand and Vietnam. Progress in UXO clearance rates and international funding levels for these efforts will be critical. Any reports of increased violence or instability in Xaisomboun Province or along the Burma border should be closely watched. Furthermore, the economic stability of Laos, particularly its debt obligations to China and efforts to attract foreign investment, will indirectly influence its security posture and capacity for self-reliance.

Strategic recommendations: Laos should prioritize securing sustained international funding for UXO clearance and victim assistance programs, potentially leveraging its leadership role in the CCM. Strengthening law enforcement capabilities and intelligence sharing with neighboring countries is crucial for effectively combating transnational organized crime, including drug trafficking and cyber scams. Internally, the government should focus on addressing the root causes of unrest in Xaisomboun Province through development initiatives and dialogue, alongside security measures. Diversifying defense partnerships, while maintaining strong ties with China and Vietnam, could enhance Laos's strategic autonomy and resilience against external pressures.
