Russia's biggest banks were put on the EU's blacklist.
Brussels expanded the list of persons subject to travel bans and assets freezes and took a number of restrictive measures in relation to Crimea.
The decision was taken in Brussels on Monday at a meeting of the Permanent Representatives Committee (Coreper), UNIAN reports.
The permanent representatives agreed to add more persons and companies that benefit from or support Russian decision makers (the so called associates) to the list of people and entities subject to assets freezes and travel bans.
They also agreed to impose sanctions on those responsible for actions that violate the territorial integrity of Ukraine. The list includes eight individuals and three entities.
The Wall Street Journal says with a link to diplomatic sources that sanctions will target five individuals and two entities.
Sanctions will sharply limit the ability of Russia's two largest banks, Sberbank and VTB, according to WSJ.
