- Russia's share of new ASEAN defense contracts collapsed from roughly 20% during 2017–2021 to under 3% in 2022–2024, with new Russian orders all but disappearing except for backlog deliveries like Myanmar's Su-30SMEs.
- Suppliers outside the US–China–Russia "big three" — France, South Korea, Turkiye, and India — now account for about 85% of Southeast Asian defense contract value, as China conspicuously failed to fill the gap Moscow left.
- The Philippines canceled a November 2021 contract for 16 Russian Mi-17 helicopters after the Ukraine invasion made the deal a sanctions trap, switching to Poland-built S-70i Black Hawks with $100 million in US Foreign Military Financing to offset the cancellation.
- Vietnam — long built around Russian Su-30s, Kilo-class submarines, and S-300 air defenses — signed a $245 million deal for South Korean K9 howitzers, deepened submarine sustainment cooperation with India, and is expected to ink a $100 million deal for used US C-130 transport planes.
- Malaysia purchased 18 South Korean FA-50 fighters and three Turkish ANKA drones in 2023 because sanctions made maintaining its 18 Su-30MKMs increasingly difficult; the new platforms offer Link-16 and NATO-compatible command-and-control that Russian aircraft cannot interface with.
- ASEAN is splitting along geographic lines — maritime states (Philippines, Indonesia, Singapore) are integrating deeper with Western military structures while mainland states (Cambodia, Laos, Myanmar) tilt further toward China, eroding the bloc's traditional non-alignment posture.
Why it matters: The collapse of Russia's arms pipeline is locking Southeast Asian militaries into Western logistics, training, and software networks for decades. Contractual sustainment arrangements and training pipelines raise the cost of leaving the Western ecosystem with each passing year, narrowing ASEAN's strategic autonomy and making studied neutrality harder to maintain as the region's maritime and mainland states drift toward opposite poles.
