U.S. President Joe Biden will speak by phone to Ukrainian President Volodymyr Zelenskiy on Monday ahead of a summit between Biden and Russian leader Vladimir Putin, said Mykhailo Podolyak, an adviser to Zelenskiy's chief of staff.
"Today there will be a telephone conversation between the presidents of Ukraine and the United States, which will allow us to compare positions on a number of important issues on the global agenda."
Putin and Biden will meet in Geneva on June 16, amid sharp disagreements over election interference, human rights and Ukraine.
