Indonesia has deepened its defence cooperation with Belarus, walking a careful line between breaking free from historic supply bottlenecks and entangling its military logistics in new political risks, East Asia Forum reported.
When Belarusian President Aleksandr Lukashenko visited Jakarta in July 2026, the two governments launched a cooperation roadmap and signed seven agreements, though none of those specific pacts touched directly on defence. Yet, as East Asia Forum detailed, Jakarta’s military ties with Minsk have quietly expanded over the past decade as part of a wider post-1999 strategy to diversify arms suppliers and avoid single-source vulnerability.
That diversification strategy traces its roots back to an American arms embargo imposed in 1999, which forced Indonesia to seek alternative military hardware. Military leadership declared in 2002 that the country would not continue to be dependent on one source, leading Jakarta to purchase four Sukhoi fighters and two Mi-35 helicopters from Russia in 2003.
Maintaining those fleets over decades creates a gravitational pull toward the original equipment families, since spare parts and trained crews are already in place. When two new Mi-35M helicopters arrived from Russia in September 2026, the Indonesian defence ministry justified the acquisition by citing the clear operational benefits of continuity with the older Mi-35P fleet.
Belarus services aircraft through bilateral agreements, including a 2013 maintenance pact and a March 2025 agreement covering Sukhoi fighter jet maintenance, drones, munitions, and special forces training. This engagement has moved ahead of any public procurement decisions, highlighted by Belarusian offers of the Buk-MB2K air defence system at a Jakarta exhibition in June 2025 and subsequent training completed by Indonesian army officers in Belarus.
While Indonesia’s supplier base has expanded from 12 to 26 countries since the 1999 US embargo—evidenced by the delivery of French Rafales in January and May 2026 alongside US-built Apache helicopters—this broad mix brings its own logistical strain. Researchers have warned that Jakarta now risks over-diversification, which burdens military supply chains with too many separate equipment families to maintain simultaneously.
The partnership with Belarus also introduces latent financial hazards, particularly because two of the July 2026 agreements link Indonesian financial regulators and intelligence units with Belarusian authorities. With European Union sanctions on Belarus remaining in force until February 28, 2027, and Jakarta aiming to sign its own economic partnership agreement with the EU by the end of November 2026, it remains unclear how Brussels will interpret these intersecting financial links.
