US weighs additional sanction steps as Russia shifts war footing, White House says

The US and its partners are ready to use sanctions and export controls to prevent China-Russia trade that threatens security amid the Ukraine war, said a White House official. White House deputy National Security Adviser for International Economics Daleep Singh said the G7 leaders' summit next month was the best chance to shore up Ukraine's financing gap by working out a plan to monetize around $300 billion in frozen Russian assets, a move he said was risky but necessary.
