President Donald Trump’s deadline for Russia to end its war in Ukraine or suffer severe economic punishment expires Friday, but it’s unclear how he plans to proceed amid new efforts toward a summit with Vladimir Putin and delicate trade negotiations with China.

Earlier Thursday, when pushing back on Kremlin claims that a Trump-Putin summit had been set, a White House official had said Putin would also have to meet with Zelenskyy for the meeting to take place -- something the Kremlin has not been willing to commit to so far.

Trump has met in-person with Zelensky at least three times since returning to office, including a Feb. 28 meeting where he lashed out at the Ukrainian president and accused him of prolonging Russia’s invasion. The two leaders met again on April 26 on the sidelines of Pope Francis’ funeral and in The Hague on June 25.
