Overview

  • Chinese-made L550E engines are covertly shipped to state-owned IEMZ Kupol through front firms Beijing Xichao, SMP-138 and LIBSS under the guise of industrial refrigeration units.
  • An internal Kupol document reveals a 2025 contract with Russia’s defense ministry for over 6,000 Garpiya-A1 drones, up from 2,000 in 2024, with more than 1,500 delivered by April.
  • The Ukrainian military intelligence agency reports Russia deploys about 500 Garpiya-A1 kamikaze drones each month against civilian and military targets deep inside Ukraine.
  • Sanctions imposed on Xiamen Limbach and other suppliers have failed to halt engine deliveries, highlighting loopholes in controls on dual-use goods.
  • European leaders, including Ursula von der Leyen, are intensifying diplomatic pressure on China to tighten export regulations before a summit with Xi Jinping.
