"Today, the US Department of the Treasury’s Office of Foreign Assets Control (OFAC) designated eight individuals and one entity in response to Russia’s continued aggression toward Ukraine and attempted occupation of Crimea", the Treasury said.
Prime Minister or the Republic of Crimea Yuri Gotsanyuk and Chairman of the Legislative Assembly Vladimir Nemtsev are among the sanctioned individuals.
The Treasury also targeted chairman of Sevastopol Election Committee Sergei Danilenko, his deputy Lidia Basova, the Committee's Secretary Ekaterina Pyrkova and the member of the Federal Council of the Russian Federation, representing Sevastopol, Ekaterina Altabaeva.
Canada designated the same individuals along with the US, while the European Union (EU) imposed sanctions against seven of the individuals on Tuesday, the Treasury said.
The US also designated the Moscow-based Grand Service Express company, which provides railroad transportation between mainland Russia and Crimea, along with its CEO Alexander Ganov.
The US and EU have introduced several rounds of sanctions on Russia since 2014, when Crimea held a referendum in which 97 percent of voters supported reunification with Russia.
Western countries and Kiev have not recognized the legitimacy of the referendum.
Moscow has denied any interference in Ukraine's affairs and insisted that the referendum was carried out in line with international law.
