Ukraine's task this year is not only to maximally strengthen its air shield and long-range capabilities, but also to inflict maximum systemic losses on Russia, Ukrainian President Volodymyr Zelenskyy said in a video message on Wednesday.

In particular, he noted "this applies to frozen Russian assets, both of the terrorist state and of individuals associated with it. Everything must be confiscated and used for defense against terror. It is fair to retaliate against a terrorist. It is fair to destroy terrorists. And it is fair to make the terrorist state pay for its actions."

"And we are working with our partners as vigorously as possible to ensure a decision on Russian assets as soon as possible," he said, noting that he spoke about this on Wednesday at a meeting with the head of European diplomacy, Borrell.

"We really need a unified and strong decision. A decision that proves our common respect for international law and absolute contempt for the terrorist state," Zelenskyy said.
