## What to know

- The International Energy Agency reported on June 1, 2026 that China controls 91% of global rare-earth refining capacity and 94% of sintered permanent-magnet production.
- Global motor engineers have sought chemical alternatives to mitigate price swings in cobalt and heavy rare-earth additives.
- Academic teams at the Institute of Physics under the Chinese Academy of Sciences published basic experimental results in February 2025 on high-entropy rare-earth magnetic systems.

China's Ministry of Commerce maintained strict export licensing on rare-earth permanent magnets as automotive motor and industrial drive manufacturers assessed the limits of multi-principal high-entropy alloy research, according to ministry regulatory records on Sept. 1, 2026.

The International Energy Agency reported on June 1, 2026 that China controls 91% of global rare-earth refining capacity and 94% of sintered permanent-magnet production. That processing concentration leaves Western powertrain developers and robotics suppliers dependent on Chinese metal converters and sinter facilities for high-performance drive components.
