US and European officials met at US Treasury Department on Monday evening to discuss various forms of economic pressure to exert on Russia, including new sanctions and tariffs on Russian oil purchases, a person familiar with the meeting told The Associated Press.

The person, who spoke on the condition of anonymity to discuss the meeting, said US officials emphasised to their European counterparts that President Donald Trump is willing to exert significant actions to end the war but expects full cooperation from European partners in whatever actions are taken.
