Ukraine's Foreign Minister Dmytro Kuleba has thanked his UK counterpart Liz Truss for London's decision to introduce large-scale sanctions against Russia.
"The UK continues to demonstrate leadership in global efforts to deter Russia from further aggression. Measures such as sanctioning Russian financial interests in the UK can hit Russia where it hurts," he tweeted.
