The US has marked a year since Russia invaded Ukraine by announcing a new range of sanctions against Russia and new military aid for Ukraine.
The latest restrictions target more than 100 entities both within Russia and worldwide, including banks and suppliers of defence equipment.
Specifically, the US said it wants to stop those helping Russia exploit loopholes to get sanctioned materials.
The White House's fresh round of aid for Ukraine is worth $2bn (£1.7bn).
A further $550m (£459m) will be supplied to both Ukraine and neighbouring Moldova to strengthen their energy infrastructure.
"One year on, the commitment of the United States, together with some 50 countries who have rallied to rush urgently needed assistance to Ukraine, has only strengthened," the Department of Defense said. บาคาร่า6699
