The United States has intensified its sanctions regime against Russia in response to the ongoing conflict in Ukraine, targeting a wide array of entities and individuals involved in the war effort, evasion of sanctions, and sectors crucial to Russia's economy. The US Department of the Treasury has imposed full blocking sanctions on Sovcomflot, Russia's largest state-owned shipping company, along with 14 of its oil tankers. Additionally, over 250 entities and individuals have been sanctioned by the US State Department for their involvement in Russia's war effort, including those in the energy, metals, and mining sectors, and for the illegal displacement of Ukrainian children. On February 24, the Department of Justice took action by arresting Russian oligarchs and seizing assets worth $2.5 million. Furthermore, the US Department of Commerce has introduced new export restrictions on 93 companies supporting Russia's military-industrial complex. Amid these developments, Russia has activated its price floor mechanism to protect its state budget from Western energy sanctions, with oil producers bearing the cost. The US has also issued a Business Advisory highlighting the risks of doing business in Russia, including the kleptocratic environment and the potential for complicity in war crimes. Meanwhile, the Pentagon is investigating over 50 cases of theft, fraud, and corruption linked to Ukrainian aid, revealing challenges in monitoring the billions of dollars sent to Ukraine.
