HRH Prince 'Abdul Mateen also addressed the escalating tensions in the Middle East, particularly the question of Palestine, calling for a permanent ceasefire, unhindered humanitarian access, and the protection of civilians. He reaffirmed Brunei's support for an independent and sovereign State of Palestine based on pre-1967 borders with East Jerusalem as its capital. This participation highlights Brunei's active role in global diplomacy and its stance on critical international issues.

  Brunei's Ministry of Foreign Affairs issued a statement on September 25, 2026, addressing escalating tensions in the Middle East, expressing solidarity with regional stability, urging the protection of civilian infrastructure, and reaffirming the importance of maritime passage under international law. This followed an earlier statement on September 19, 2026, expressing deep concern over an attempted drone attack near Makkah Al-Mukarramah on September 15, 2026. Brunei stressed the importance of safeguarding freedom of navigation, particularly through the Strait of Hormuz, as vital to international trade, energy security, and global supply chains. These statements reflect Brunei's concern for regional stability beyond Southeast Asia and its advocacy for international law and humanitarian principles.

• Brunei Co-Chairs Sub-Regional Counter-Terrorism Forum
  Brunei Darussalam and Thailand are set to co-chair the Senior Officials' Counter-Terrorism Policy Forum under the Sub-Regional Meeting on Counter-Terrorism and Transnational Crime (SRM) this year. Brunei also presented a concept paper on a proposed sub-regional framework for assessing public sentiment towards extremist and terrorist ideologies spread through online platforms. This initiative aims to strengthen regional efforts by establishing a mechanism to measure the effectiveness of counter-terrorism and counter-extremism initiatives. This ongoing engagement highlights Brunei's proactive approach to combating terrorism and violent extremism through regional cooperation and innovative policy development.

Geopolitical Impact and Regional Dynamics

Brunei's security developments during this period underscore its consistent foreign policy of maintaining friendly relations, promoting regional peace, and adhering to multilateralism. The conclusion of CARAT Brunei 2026 with the United States and the ongoing Exercise Dusk Leopard 2026 with Australia demonstrate Brunei's commitment to strengthening defense partnerships with key Indo-Pacific allies. These exercises enhance interoperability and maritime security capabilities, contributing to regional stability, particularly in the context of the South China Sea, where freedom of navigation remains a critical concern. The active participation in these drills signals Brunei's intent to contribute to a rules-based international order and balance regional power dynamics.

The official visit of the Crown Prince to Singapore and the signing of an MOU on maritime and port development further solidify Brunei's bilateral ties within ASEAN. This relationship, celebrating its 50th anniversary of defense relations, serves as a model for sustained cooperation in defense, economic, and digital sectors, reinforcing ASEAN's collective strength. Brunei's hosting of the ReCAAP ISC Cluster Meeting 2026 also positions it as a key player in addressing transnational maritime crimes like piracy, which directly impacts regional trade and security.

Brunei's diplomatic statements at the UN General Assembly, particularly concerning the Middle East conflict and the call for a two-state solution for Palestine, reflect its broader commitment to international peace and humanitarian principles as a Muslim-majority nation. These statements, alongside concerns about the Strait of Hormuz, highlight Brunei's awareness of how global events can impact its own energy security and economic stability. The ongoing defense cooperation with Russia, as evidenced by the second Joint Working Group meeting, indicates a diversified approach to defense partnerships, allowing Brunei to maintain strategic flexibility in a complex geopolitical landscape.

Military and Defense Analysis

The Royal Brunei Armed Forces (RBAF) demonstrated a robust and multifaceted approach to defense during this period, focusing on both internal readiness and external partnerships. The commencement of Exercise Hikmat Bersatu VII/2026 across all four districts of Brunei underscores the RBAF's commitment to maintaining a high level of domestic operational readiness, encompassing land, sea, and air components. The inclusion of explosives and pyrotechnics in the exercise suggests realistic training scenarios designed to test and enhance combat effectiveness.

Internationally, the RBAF's participation in CARAT Brunei 2026 with the United States highlights a continued emphasis on maritime security and interoperability with a major global power. The exercise's focus on anti-submarine warfare and maritime interdiction operations indicates a strategic interest in protecting Brunei's maritime domain and contributing to regional naval capabilities in the South China Sea. Similarly, the involvement of Brunei's special forces in Exercise Dusk Leopard 2026 with Australia demonstrates a dedication to developing specialized capabilities, particularly in counter-terrorism and close combat, through advanced training with a highly capable partner. The 50th anniversary of defense relations with Singapore, marked during the Crown Prince's visit, further solidifies a long-standing and mutually beneficial defense partnership, likely involving ongoing professional exchanges and joint exercises. While specific defense spending figures were not available in the provided news, the consistent engagement in these high-level exercises and diplomatic defense dialogues suggests a sustained investment in modernizing the RBAF and enhancing its capabilities through training and international cooperation.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, Brunei is likely to continue its active engagement in regional security dialogues and exercises. The ongoing Exercise Hikmat Bersatu VII/2026 will conclude, providing the RBAF with valuable insights into its domestic operational readiness. We can anticipate further diplomatic efforts to follow up on the outcomes of the UN General Assembly and the Singapore-Brunei Young Leaders' Programme, potentially leading to concrete initiatives in areas like maritime and port development, and digital and green economies. Brunei's commitment to cybersecurity will likely see continued development, building on the success in the Cyber Battle: Capture the Flag competition and the discussions at the CySec 2026 conference. The co-chairmanship of the Senior Officials' Counter-Terrorism Policy Forum will also likely see Brunei taking a more prominent role in regional counter-terrorism strategy.

Critical flashpoints and risk areas: The South China Sea remains a critical flashpoint, with ongoing maritime security concerns and the need to uphold freedom of navigation. While Brunei maintains a measured approach, any escalation of tensions in the broader region could indirectly impact its security and economic interests. The Middle East conflict continues to be a significant concern for Brunei, as articulated at the UNGA, due to its humanitarian impact and potential for wider regional instability that could affect global energy markets and supply chains. Domestically, while no immediate threats were reported, the RBAF's nationwide exercise highlights the importance of internal security and readiness against unforeseen contingencies.

Indicators to monitor: Key indicators to monitor include any new developments or incidents in the South China Sea involving claimant states, which could influence Brunei's maritime security posture. The progress and outcomes of regional counter-terrorism initiatives, particularly those stemming from the forum co-chaired by Brunei, will be important to assess the evolving threat landscape. Further announcements or collaborations in cybersecurity, especially regarding critical infrastructure protection and AI integration, would indicate the direction of Brunei's digital defense strategy. Additionally, the nature and frequency of Brunei's diplomatic engagements with major powers (e.g., US, China, Russia, EU) and its ASEAN partners will provide insights into its strategic alignments and efforts to maintain regional balance.

Strategic recommendations: Brunei should continue to prioritize and invest in its maritime security capabilities, given the strategic importance of its territorial waters and the South China Sea. Sustaining and expanding bilateral and multilateral defense exercises with trusted partners like the US, Australia, and Singapore will be crucial for enhancing interoperability and collective security. Furthermore, a proactive approach to cybersecurity, including continued investment in talent development and critical infrastructure protection, is essential in the face of evolving digital threats. Diplomatically, Brunei should maintain its principled stance on international law and peaceful dispute resolution, particularly in regional forums and the UN, to safeguard its national interests and contribute to global stability. Diversifying defense partnerships, as seen with Russia, can also offer strategic flexibility.
