The United States imposed sanctions on more than a dozen companies in China and Hong Kong for their support of Russia’s war in Ukraine as part of a tranche of nearly 300 new sanctions unveiled Wednesday.

The move comes after repeated warnings from top US officials, including Treasury Secretary Janet Yellen and Secretary of State Antony Blinken, to top Chinese officials that they must crack down on China’s provision of dual-use items to Russia that the US says are being used to strengthen its military in the war against Ukraine.

“The almost 300 targets being sanctioned by both Treasury and the Department of State include sanctions on dozens of actors that have enabled Russia to acquire desperately needed technology and equipment from abroad,” the Treasury Department said in a news release.

The sanctions also hit targets within Russia, as well as Azerbaijan, Belgium, Slovakia, Turkey and the United Arab Emirates.

The sanctions are aimed at cracking down on sanctions evasion and support for Russia’s military-industrial base and its biological and chemical weapons programs. The Treasury Department also targeted those involved in providing precursor materials to Russia used in explosives.
