  On September 29, 2026, the Royal Brunei Armed Forces (RBAF) announced the postponement of its large-scale joint military exercise, Exercise Hikmat Bersatu VII/2026.

• Brunei's Stance on South China Sea
  Brunei reiterated its commitment to the maintenance of peace, stability, and security in the South China Sea, emphasizing the importance of the 1982 United Nations Convention on the Law of the Sea (UNCLOS) and working towards the early conclusion of an effective Code of Conduct (COC). Brunei is a claimant state but does not occupy any maritime features or maintain a military presence in the disputed Spratly Islands.

Geopolitical Impact and Regional Dynamics

Brunei's diplomatic and security activities during this period underscore its consistent foreign policy of maintaining strong bilateral relationships and actively participating in multilateral forums to ensure regional stability. The Crown Prince's visit to Singapore and the launch of Exercise Vanguard signify a deepening of defense ties with a key ASEAN partner, reinforcing a network of security cooperation in Southeast Asia. The signing of the Maritime Cooperation MoU with Singapore further strengthens regional maritime security frameworks, particularly in areas of digitalization and safety, which are crucial for the busy shipping lanes of the Malacca Strait and South China Sea.

The 35th anniversary of diplomatic relations with China, marked by high-level exchanges, highlights Brunei's balancing act in the region. While maintaining close security ties with the United States and ASEAN partners, Brunei also seeks to deepen comprehensive strategic cooperation with China, including in defense. This approach reflects Brunei's economic reliance on China and its pragmatic engagement with major powers, aiming to leverage relationships for national development while navigating complex geopolitical currents, particularly concerning the South China Sea. Brunei's consistent call for adherence to UNCLOS and an early Code of Conduct in the South China Sea, reiterated at the UNGA, reflects a shared ASEAN desire for a rules-based order amidst ongoing territorial disputes.

The Minister of Foreign Affairs' visit to the CIA in the US, following UNGA engagements, demonstrates Brunei's commitment to intelligence sharing and understanding global security dynamics with a major Western power. This engagement, alongside discussions on trade and investment with the US Secretary of Commerce, indicates a multifaceted approach to its relationship with the United States, encompassing both security and economic dimensions. Brunei's active participation in the UNGA, addressing global issues like the Gaza conflict, also positions it as a responsible international actor, contributing to broader global security discourse.

Military and Defense Analysis

The Royal Brunei Armed Forces (RBAF) continues to prioritize interoperability and capacity building through international exercises and partnerships. The recent conclusion of CARAT Brunei 2026 with the United States, focusing on advanced maritime warfare and domain awareness, demonstrates a commitment to enhancing naval capabilities in the South China Sea. The launch of Exercise Vanguard with Singapore's Air Force signifies a new phase of air defense cooperation, building on five decades of defense relations and likely involving joint training and strategic planning.

The postponement of Exercise Hikmat Bersatu VII/2026 due to haze underscores a vulnerability to environmental factors, which could impact operational readiness and necessitate adaptive planning for future large-scale exercises. While no new defense acquisitions were reported within this specific week, the recent establishment of a new drone squadron for surveillance and intelligence gathering along Brunei's land borders and maritime domain (reported September 22, 2026) indicates a modernization trend towards enhancing intelligence, surveillance, and reconnaissance (ISR) capabilities. Brunei's defense spending trends are generally geared towards maintaining a professional force capable of protecting its territorial integrity and Exclusive Economic Zone (EEZ), particularly given its hydrocarbon resources. The emphasis on multilateral exercises and diplomatic defense engagements suggests a strategy of collective security and capacity building rather than a rapid, large-scale arms buildup.

Outlook and Forecast

Short-term trends (1-3 months):
In the immediate future, Brunei is likely to continue its active diplomatic engagement within ASEAN and with key dialogue partners. The newly launched Exercise Vanguard with Singapore will likely see initial planning and preparatory activities, deepening air force cooperation. The postponed Exercise Hikmat Bersatu VII/2026 will likely be rescheduled once air quality improves, demonstrating the RBAF's commitment to maintaining readiness. Brunei will also continue to participate in regional forums addressing transnational crime and maritime security, building on the recent ASEAN Law Enforcement Conference and ReCAAP meeting outcomes. Cybersecurity initiatives, spurred by recent international successes and conferences, will likely see further development in critical infrastructure protection and AI integration.

Critical flashpoints and risk areas:
The South China Sea remains a persistent flashpoint, with Brunei's claims, albeit quiet, intersecting with those of other nations and major powers. While Brunei maintains a non-confrontational stance, any escalation in the broader South China Sea could indirectly impact its maritime security and economic interests, particularly its offshore energy resources. Environmental factors, specifically haze and air quality, pose an operational risk, as demonstrated by the recent exercise postponement. This could affect military training, public health, and economic activities. The broader Middle East tensions, which Brunei addressed at the UNGA, could have indirect economic and security implications, particularly concerning energy markets and global supply chains, given Brunei's reliance on hydrocarbon exports.

Indicators to monitor:
Key indicators to monitor include the rescheduling and successful execution of Exercise Hikmat Bersatu VII/2026, which would signal improved environmental conditions and sustained military readiness. Progress on the Singapore-Brunei Exercise Vanguard framework will indicate the depth of bilateral air force cooperation. Further statements or actions regarding the South China Sea Code of Conduct will be crucial for regional stability. Any new defense acquisitions or modernization announcements, particularly related to maritime or air assets, would signal shifts in defense priorities. Continued high-level diplomatic exchanges with both Western and Eastern powers will reflect Brunei's strategic balancing act.

Strategic recommendations:
Brunei should continue to invest in environmental monitoring and mitigation strategies to minimize the impact of haze on national security operations and public health. Strengthening maritime domain awareness capabilities through technology and regional partnerships, building on the ReCAAP discussions and the MoU with Singapore, is crucial for protecting its EEZ and addressing transnational maritime crimes. Brunei should also continue its active role in ASEAN-led mechanisms to promote dialogue and peaceful resolution of disputes in the South China Sea. Further development of cybersecurity capabilities, particularly in AI-driven defense and critical infrastructure protection, is essential to safeguard its digital economy and national security interests. Finally, maintaining a diversified diplomatic strategy with major powers like the US and China, while strengthening ASEAN centrality, will be vital for navigating complex geopolitical landscapes and securing Brunei's long-term interests.
