The United States on August 23 added nearly 400 individuals and entities in and outside of Russia to its sanctions list as part of the U.S. effort to disrupt Russia's international supply chains, metal procurement, and financial services that support its war effort in Ukraine.

The U.S. Treasury Department said the move was building on sanctions already imposed on Russia in response to its full-scale war in Ukraine and were aimed at distinct networks, individuals, and entities whose products and services enable Russia to sustain the war and evade sanctions.

"Russia has turned its economy into a tool in service of the Kremlin’s military industrial complex," Deputy Secretary of the Treasury Wally Adeyemo said in a news release . The treasury's "actions today continue to implement the commitments made by President [Joe] Biden and his G7 counterparts to disrupt Russia's military-industrial base supply chains and payment channels." The sanctions target numerous transnational networks, the department said.

Among them are those allegedly involved in procuring ammunition and military materiel for Russia, facilitating sanctions evasion for Russian oligarchs through offshore trust and corporate formation services, laundering gold for a sanctioned Russian gold company, and supporting Russia's military-industrial base by procuring sensitive and critical items such as advanced machinery tools and electronic components. The list of companies designated for new sanctions includes 60 Russia.
