The United States has slapped sanctions on several Russian technology firms, including its largest chipmaker, and people associated with them over Russia’s invasion of Ukraine.

The U.S. Treasury Department said in a statement on March 31that it imposed sanctions on 13 people and 21 entities, including Joint Stock Company Mikron, the largest Russian manufacturer and exporter of microelectronics and Russia’s largest chipmaker.

The U.S. Treasury said the sanctions target networks and technology companies that are “instrumental” to Russia’s invasion of Ukraine.

The department also expanded authorities to include the aerospace, marine, and electronics sectors of the Russian economy, allowing Washington to impose penalties on any person or entity determined to operate in those sectors.

The move also takes aim at “malicious cyber actors,” the Treasury Department said.

“Russia not only continues to violate the sovereignty of Ukraine with its unprovoked aggression but also has escalated its attacks striking civilians and population centers,” Treasury Secretary Janet Yellen said in a news release.

“We will continue to target Putin’s war machine with sanctions from every angle, until this senseless war of choice is over,” she added.
