The U.S. Treasury has announced sanctions against two Chinese makers of drone engines and parts that the Biden administration says directly helped Russia build long-range attack drones used in the war in Ukraine.

The US Treasury announces the move after the Ukrainian president called out China's involvement in Russian arms.
