Key Takeaways

India's oldest strategic partnership is navigating the Ukraine war, a dramatic surge in oil imports, Western sanctions pressure, and Russia's deepening embrace of China — all while defence dependency keeps the relationship anchored.

  • Russia supplied 60-65% of India's military equipment historically, though this has declined to ~45% as India diversifies to US, France, and Israel
  • India's oil imports from Russia surged from 2% to 35% of total crude imports after the Ukraine war, saving an estimated $15 billion annually
  • The S-400 Triumf air defence system deal ($5.4 billion) proceeded despite US CAATSA sanctions threat, demonstrating India's strategic autonomy
  • Bilateral trade reached a record $65 billion in 2025-26, driven overwhelmingly (85%) by Indian oil purchases
  • Growing Russia-China military axis and delayed defence deliveries are pushing India toward greater diversification

Supporting Evidence
  • While Russia has historically been India's primary defence supplier, deliveries of S-400 systems have been delayed, spare parts availability dropped by 40% since 2022, and Russia has prioritised its own military needs. India's defence imports from Russia fell to 36% (2020-24) from 62% (2014-18).
