The European Union Council on Tuesday imposed a fourth package of economic and individual sanctions, including restricting the export of luxury goods to Russia and banning new investments in Russia's energy sector.
Sanctions also target "key oligarchs, lobbyist and propagandists pushing the Kremlin’s narrative on the situation in Ukraine," the Council said in a statement.
"The aim of the sanctions is that President Putin stops this inhuman and senseless war," Josep Borrell, High Representative of the European Union for Foreign Affairs and Security Policy, said in a statement.
The United Kingdom is expanding sanctions targeting over 300 people including former Russian President Dmitry Medvedev and oligarchs with an estimated worth of more than $94 billion.
The U.S. is also expanding sanctions, including against Russian Ministry of Defense officials.
The State Department is also implementing a new visa ban policy against Russian officials who have "cracked down on Russian citizens who have taken to the streets to protest their government's brutal campaign in Ukraine" and "are responsible for suppressing dissent in occupied areas of Ukraine."
In retaliation for sanctions from the U.S., Russia’s foreign ministry has announced personal sanctions against President Joe Biden and many top administration officials including Secretary of State Antony Blinken and Secretary of Defense Lloyd Austin. The sanctions also target Biden’s son, Hunter, and former Secretary of State Hillary Clinton.
