The USA has published the list of people subject to sanctions, which includes several Russian and Ukrainian officials.
Their assets in the US will be frozen, and Americans will be banned from getting into business contacts with the officials on the list.

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.
