"The Biden administration announced expanded sanctions against Russia's energy sector, targeting oil and liquefied natural gas as a response to the war in Ukraine. The sanctions could cost the Russian economy billions of dollars monthly and target over 180 oil-carrying vessels linked to evading sanctions. Both the United States and British officials are imposing sanctions on major Russian oil producers, including Gazprom Neft and Surgutneftegas. The Kremlin dismissed the sanctions, while President-elect Donald Trump's administration will decide whether to maintain or roll them back after taking office."
