Report: Russian drone designs and wind-tunnel testing aid China's arms buildup

An investigation reveals that Russian rocket-launched drone designs likely influenced Chinese weapons unveiled in 2025, and Russian wind tunnels continued testing models for China's top arms maker after the 2022 invasion of Ukraine. This indicates sustained defense-industrial collaboration between Moscow and Beijing despite Western sanctions, potentially accelerating China's military drone capabilities. The extent and scope of the cooperation remain partially unclear, but the report suggests a deepening of military-technical ties.
