WASHINGTON, March 20. /ITAR-TASS/. The USA imposes further sanctions against Russia in addition to that already introduced earlier this week with regard to Moscow’s policy towards Ukraine. US President Barack Obama stated this on Thursday.

The American leader specified that the new measures are imposed against Russian high-ranking officials and other people who did not belong to authorities in Moscow, but who, as Washington believes, support actions of the Russian government against Ukraine. Obama added that one Russian bank was also included in the list. However, the president did not disclose the name of the bank.

Spokesperson of the US administration later specified during a telephone briefing for journalists that the new list included 20 Russian officials.

Obama said he has signed on Thursday a new executive order allowing the US administration to apply sanctions against key sectors of Russian economy. However, the president acknowledged that applying such measures might have negative impact on the whole global economy.

On Monday, Obama warned that the US would introduce additional sanctions against Russia, if it continues interfering with Ukraine’s affairs.

March 17, USA published a black list of Russian and Ukrainian officials. The list includes presidential aide Vladislav Surkov, presidential adviser Sergei Glazyev, Head of State Duma Committee for CIS Affairs Leonid Slutsky, Head of Federation Council's Committee for constitutional legislation Andrei Klishas, Federation Council Speaker Valentina Matviyenko, Deputy Prime Minister Dmitry Rogozin, Chair of the Duma committee for family, women and children affairs Yelena Mizulina, Crimean Prime Minister Sergey Aksyonov, Crimean State Council Speaker Vladimir Konstantinov, leader of the Ukrainian Choice public movement Viktor Medvedchuk and Ukrainian president Viktor Yanukovych.

Their assets in the US will be frozen, and Americans will be banned from getting into business contacts with the officials on the list.

Apart from that, a new executive order of the US president has been adopted. This order forms the basis of sanctions against the aforementioned persons. In addition, the document allows introducing punitive measures against persons and organizations serving the interests of Russia’s military industry, as well as providing material support to people included in the black list.
