A fresh round of European Union sanctions against Russia has cleared its final legal hurdle a day before the second anniversary of the full-scale invasion of Ukraine.

"We are further tightening the restrictive measures against Russia's military and defense sector," EU foreign policy chief Josep Borrell said in a press release. 

Senior diplomats from the EU's 27 member states agreed on the sanctions on Wednesday in Brussels, but final approval was still required from EU capitals. That was green-lighted on Friday.

The 13th package of sanctions target the Russian defense industry, including export restrictions on technologies such as aerial drone components.

They also set their sights on target countries "who supply equipment [to Russia] as well as those responsible for the illegal deportation and military re-education of Ukrainian children."

The sanctions impose restrictions on organizations in countries including China, India, Kazakhstan, Serbia, Sri Lanka, Kazakhstan, Thailand, and Turkey, for "supporting Russia's military and industrial complex."

They also include asset freezes and travel bans on 106 individuals and 88 organizations.

The suite of measures mean that some 2,000 people and groups are now sanctioned by the EU for "undermining or threatening the territorial integrity, sovereignty and independence of Ukraine."

The round of prohibitions stops EU citizens and companies from making money available to sanctioned entities, a full list of which is to be published by tomorrow in the EU's statute book.
