Ukraine’s President Volodymyr Zelensky raised the stakes ahead of a potential meeting with Vladimir Putin in Turkey on Thursday by saying he wouldn’t hold talks with any Russian representative other than the president himself.

President Volodymyr Zelensky of Ukraine said that if President Trump attended the talks, it would put pressure Russia’s leader, Vladimir V. Putin, to meet face-to-face.

Putin hasn't yet said whether he will be at the talks, which Trump has urged Ukraine and Russia to attend as part of Washington's efforts to stop the fighting.
