"The Russian Federation must immediately cease its aggression against Ukraine and return to fulfilling its international legal and political obligations. In the event of further continuation and escalation of aggressive actions by Russia against Ukraine, the response of the international community must be adequate, and sanctions must be strengthened," the statement says.

Foreign Minister Dmytro Kuleba via Twitter welcomed the EU decision to extend Russia sanctions for undermining the territorial integrity, sovereignty, and independence of Ukraine.

"I welcome EUCouncil's decision to extend sanctions on 177 persons & 48 entities involved in Russian aggression against Ukraine. EU sanctions should remain until Ukraine's sovereignty & territorial integrity are fully restored. Russia must cease its aggression against Ukraine," Kuleba tweeted.
