These agreements also encompass critical minerals, steel joint ventures, and the joint development of strategic ports in Sabang (Aceh) and India's Andaman & Nicobar Islands, aimed at enhancing maritime security and trade.

• Military Exercises: Exercise Pacific Partnership 26
  HMAS Choules, carrying approximately 113 specialist personnel from Australia, Canada, Germany, and the United States, arrived in Sibolga, Sumatra, on July 21, 2026, for Exercise Pacific Partnership 26. Running from July 20 to August 1, 2026, this US-led activity focuses on strengthening international humanitarian assistance and disaster relief (HADR) capabilities and cooperation in the Indo-Pacific, with personnel working alongside Indonesian authorities to deliver essential services to local communities.

• Military Exercises: Exercise Orruda 2026 with Russia
  Indonesia's Navy frigate KRI I Gusti Ngurah Rai-332 arrived in Vladivostok, Russia, on July 23, 2026, to participate in the bilateral Exercise Orruda 2026 with the Russian Federation Navy. This exercise, the second iteration of such drills, includes Maritime Interdiction Operations, Unmanned Surface Vessel (USV) drills to counter drone threats, Search and Rescue (SAR) exercises, and Medical Evacuation (MEDEVAC) drills, reflecting Indonesia's commitment to strengthening military cooperation and defense diplomacy with Russia.

• Military Exercises: Garuda Canti Dharma III 2026 Peacekeeping Exercise
  The Multinational Peacekeeping Exercise 2026 (MPE26) Garuda Canti Dharma III 2026 (GCD26) commenced on July 20, 2026, at the Indonesian Peacekeeping Training Center in Bogor, West Java, and will run until August 2, 2026. This exercise involves over 700 personnel from 22 countries, including the US, Malaysia, the Philippines, Singapore, Thailand, Vietnam, the UK, Australia, and New Zealand, aiming to enhance interoperability and familiarize forces with tactics, techniques, and procedures for global peace operations.

• Military Exercises: Exercise Pitch Black 2026
  Indonesian Air Force T-50i Golden Eagle light combat aircraft were deployed to Exercise Pitch Black 2026 in Northern Australia, which began on July 20, 2026, and continues until August 7, 2026. This biennial Royal Australian Air Force exercise is a capstone international event involving 21 participating nations, with Indonesia's T-50i Golden Eagles primarily operating in the strike role, strengthening collective air power and defense relationships.

• Defense Budget and Modernization Drive
  Indonesia's 2026 defense budget stands at Rp 187.1 trillion (approximately US$10.5-10.78 billion), making the Ministry of Defense the second-highest government spending allocation. This budget reflects a steady increase over the past five years, with a significant portion (Rp 81.39 trillion) allocated for defense equipment modernization. President Prabowo Subianto aims to increase defense spending to 1.5% of GDP over his term, signaling an accelerated modernization program that includes ongoing deliveries of 42 Dassault Rafale F4 fighters, which began in 2026.

• Diplomatic Stance on South China Sea Code of Conduct
  On July 21, 2026, Indonesia's Foreign Minister Sugiono urged ASEAN counterparts in Manila to swiftly conclude the South China Sea Code of Conduct (COC), stating that "Our people have waited 24 years for rules at sea. They should not wait for another year." This call came amidst renewed clashes between Beijing and Manila in the contested waterway, with Indonesia emphasizing that the code must be "firmly anchored" in the 1982 UNCLOS. Indonesia maintains its position as a non-claimant state in the South China Sea but firmly rejects China's claims over disputed parts, particularly around the Natuna Islands, as having no legal basis.

• Counter-terrorism Assessment and National Action Plan
  Coordinating Minister for Political and Security Affairs, retired Gen. Djamari Chaniago, announced on July 27, 2026, that the terrorism threat in Indonesia is "relatively under control." He cited the Global Terrorism Index 2026 classifying Indonesia with a "medium impact from terrorism" and the Global Peace Index 2026 placing it at a "medium level of peacefulness." The government is strengthening interagency cooperation in implementing Presidential Regulation No. 8 of 2026 on the 2026–2029 National Action Plan for the Prevention and Countering of Violent Extremism Leading to Terrorism.

• Persistent Cybersecurity Threats
  A weekly cyber threat newsletter for July 12-18, 2026, highlighted that Indonesia continues to face persistent cyber threats, including ransomware, phishing, credential theft, and cyber espionage. Critical sectors such as government, financial services, telecommunications, manufacturing, energy, and retail remain high-value targets, with China-aligned and North Korea-aligned Advanced Persistent Threat (APT) groups sustaining strategic risks through cyber espionage operations across Southeast Asia. The CyberSecIndonesia Conference was held in Jakarta on July 22, 2026, to address these challenges.

• Diplomatic Push for Conflict Prevention at UNSC
  On July 25, 2026, Indonesia urged the UN Security Council (UNSC) to strengthen conflict prevention efforts and recognize regional organizations as key partners in maintaining international peace. Deputy Foreign Minister Arrmanatha Nasir, speaking at an open debate in New York, stressed the importance of dialogue, mediation, peacekeeping, and post-conflict recovery, drawing on ASEAN's experience in building trust and easing tensions.

• Maritime Security Incident: Strait of Hormuz
  Two Indonesian crew members were repatriated on July 22, 2026, after their MT Belma tanker was affected by a missile attack in the Strait of Hormuz on July 15, 2026. The Indonesian Ministry of Transportation affirmed its commitment to protecting Indonesian seafarers in emergency situations resulting from conflict or security disturbances in international shipping areas.

Geopolitical Impact and Regional Dynamics

Indonesia's security developments during this period underscore its commitment to an "independent and active" foreign policy, navigating complex regional and global dynamics. The simultaneous engagement in military exercises with both the United States (Pacific Partnership, Garuda Canti Dharma, Pitch Black) and Russia (Orruda 2026) demonstrates Jakarta's strategic balancing act. This approach aims to enhance its military capabilities and interoperability with diverse partners without aligning exclusively with any major power bloc, thereby reinforcing its non-aligned stance. The deepening strategic ties with India, including defense acquisitions and maritime infrastructure development in Sabang, signal Indonesia's intent to strengthen its influence in the Indian Ocean region and diversify its security partnerships beyond traditional actors.

The renewed push for a swift conclusion of the South China Sea Code of Conduct is a critical diplomatic effort by Indonesia to de-escalate tensions in a vital waterway. While Indonesia is a non-claimant state in the Spratly and Paracel archipelagos, its Exclusive Economic Zone around the Natuna Islands overlaps with China's expansive claims, leading to past clashes over fishing rights. Jakarta's firm stance on the legal basis of maritime claims, anchored in UNCLOS, positions it as a key advocate for rules-based order in the region. The ongoing clashes between Beijing and Manila highlight the urgency of this diplomatic initiative and Indonesia's role in fostering regional stability through ASEAN.

Relations with major powers remain dynamic. The US Secretary of War Pete Hegseth praised Indonesia's military upgrades and participation in joint exercises, emphasizing burden-sharing in collective defense. However, Indonesia's "balanced" response to the US push against "far-left terrorism" indicates a nuanced approach, where Jakarta maintains bilateral ties while asserting its sovereign framing of security threats. Meanwhile, Indonesia-China relations are entering a new phase under Presidents Prabowo and Xi, focusing on comprehensive strategic partnership across politics, economy, maritime affairs, and security. China remains Indonesia's largest trading partner, and Jakarta is keen on leveraging this relationship for economic development while urging a stronger ASEAN-China partnership for regional stability.

Military and Defense Analysis

Indonesia's military and defense posture is undergoing a significant transformation, driven by President Prabowo Subianto's accelerated modernization program. The 2026 defense budget of Rp 187.1 trillion (approx. US$10.5-10.78 billion) represents a substantial increase, though it remains around 1.0% of GDP, which is lower than some regional peers. The President has set a target of 1.5% of GDP for defense spending, indicating a long-term commitment to enhancing military capabilities.

Force modernization programs are evident across all branches. In the air domain, the Indonesian Air Force (TNI AU) has begun integrating Dassault Rafale F4 multirole fighter aircraft, with deliveries starting in 2026. The recent contract for 12 Leonardo M-346F Block 20 light fighters will further enhance combat capabilities and pilot training. Additionally, Indonesia is investing heavily in unmanned aerial systems through cooperation with Türkiye, planning to acquire and develop advanced drone technologies like the Bayraktar KIZILELMA, TB3, Akinci, and Anka-S UAV platforms to improve ISR, border security, and precision strike capabilities. Naval capabilities are also being strengthened with the ongoing construction of Scorpène Evolved submarines in cooperation with Naval Group and PT PAL Indonesia, and the development of Merah Putih-class frigates. The Letter of Intent for AW149 naval helicopters will boost maritime SAR and disaster relief.

The emphasis is not solely on acquisitions but also on strengthening the domestic defense industry and fostering technology transfer. The Leonardo M-346F deal and the AW149 LOI both include provisions for localization of support, maintenance, training, and human capital development. Similarly, the Maritime Partnership Programme with the UK, valued at £4 billion, includes technology transfer, joint research in next-generation shipbuilding, and educational collaboration. These initiatives aim to reduce long-term dependence on foreign suppliers and enhance Indonesia's strategic autonomy. Furthermore, a comprehensive military restructuring, the largest this century, is underway, involving the creation of new regional commands and strengthening air and naval components to enhance territorial coverage and integration with local communities.

Outlook and Forecast

Short-term trends (1-3 months):
In the immediate future, Indonesia will likely continue its active participation in ongoing multilateral military exercises, such as Pacific Partnership 26, Garuda Canti Dharma III 2026, and Pitch Black 2026, which are scheduled to conclude in early August. These exercises will provide valuable opportunities for enhancing interoperability and refining HADR, peacekeeping, and air combat skills. Diplomatically, Indonesia will maintain its push for the South China Sea Code of Conduct, especially as regional tensions persist. The government will also focus on implementing the newly signed defense acquisition contracts and Letters of Intent, laying the groundwork for future deliveries and domestic production capabilities. Efforts to combat street crime in Greater Jakarta will continue, building on the recent establishment of the 24/7 task force.

Critical flashpoints and risk areas:
The South China Sea remains a critical flashpoint, particularly around the Natuna Islands, where Indonesian EEZ overlaps with China's claims. Any escalation of incidents between China and other claimant states, such as the recent clash between Beijing and Manila, could indirectly impact Indonesia's maritime security interests and necessitate a stronger response. Cybersecurity poses a persistent and evolving risk, with critical sectors remaining vulnerable to ransomware, phishing, and state-sponsored cyber espionage, particularly from China-aligned and North Korea-aligned APT groups. The Strait of Hormuz incident, which affected Indonesian seafarers, highlights the vulnerability of international shipping lanes to geopolitical conflicts, requiring continued vigilance and protection for Indonesian maritime interests. While the internal terrorism threat is deemed "under control," continuous monitoring and proactive measures are essential to prevent any resurgence or new forms of violent extremism.

Indicators to monitor:
Key indicators to monitor include the progress of negotiations for the South China Sea Code of Conduct and any new maritime incidents in the region. The pace and success of Indonesia's defense modernization programs, particularly the integration of new platforms like the Rafale and M-346F, and the development of domestic defense industries, will be important. The effectiveness of cybersecurity measures and the frequency of cyberattacks on critical infrastructure should be closely watched. Furthermore, the implementation of the National Action Plan for Countering Violent Extremism and any shifts in the domestic security landscape will be crucial. Diplomatic engagements with major powers (US, China, India, Russia, EU) and regional partners will indicate the stability of Indonesia's balancing foreign policy.

Strategic recommendations:
1. Accelerate Maritime Domain Awareness and Response: Invest further in advanced maritime surveillance capabilities and rapid response assets to effectively monitor and protect Indonesia's Exclusive Economic Zone, particularly around the Natuna Islands.
2. Strengthen Cyber Resilience: Implement a comprehensive national cybersecurity strategy that includes enhanced threat intelligence sharing, robust critical infrastructure protection, and public-private partnerships to counter sophisticated cyber threats.
3. Diversify Defense Partnerships and Technology Transfer: Continue to pursue a diversified approach to defense acquisitions, prioritizing deals that include significant technology transfer and local production components to build a resilient domestic defense industry.
4. Proactive Diplomatic Engagement: Maintain a leading role in ASEAN and other regional forums to advocate for peaceful dispute resolution and the timely conclusion of a legally binding South China Sea Code of Conduct.
5. Enhance Counter-terrorism and CVE Programs: Sustain and adapt counter-terrorism efforts, focusing on intelligence-led operations, community engagement, and addressing the root causes of radicalization, in line with the National Action Plan.
