Trump has said he is considering either hitting Russia with further economic sanctions or walking away from peace talks.
“I’m going to make a decision as to what we do and it’s going to be, it’s going to be a very important decision, and that’s whether or not it’s massive sanctions or massive tariffs or both, or we do nothing and say it’s your fight,” Trump said on Friday.
Ukraine’s President Volodymyr Zelensky has repeatedly called for an unconditional ceasefire and his European allies have also insisted on a halt in fighting.
Zelensky has also accused Russia of “doing everything it can” to prevent a meeting with Putin to try to end the war.
Russia’s Foreign Minister Sergei Lavrov said Putin was ready to meet Ukraine’s leader “when the agenda is ready for a summit, and this agenda is not ready at all”, accusing Zelensky of saying “no to everything”.
