The U.S. Treasury Department has added seven Russians and dozens of companies to its sanctions list because of Moscow’s activities in Crimea and Ukraine. The updated list, released Tuesday, includes Yevgeny Prigozhin, a St. Petersburg businessman known as President Vladimir Putin’s chef. The addition of new names provoked an angry response from the Kremlin, with Deputy Foreign Minister Sergei Ryabkov vowing to get revenge. “We will be expanding our lists, we will see how we can respond asymmetrically,” Ryabkov told Russia’s TASS news agency. Prigozhin, known for his Kremlin connections, was added to the list because he provided financial and technological support to top Russian defense officials, the Treasury statement said. He has also been linked to a murky private security contractor that has sent mercenaries to Ukraine and Syria, known as ChVK Vagner. Other individuals on the updated list include executives with ties to Bank Rossiya, including Dmitry Lebedev, chairman of the bank’s board.
