Ukrainian President Volodymyr Zelensky pressed U.S. President Joe Biden to join the upcoming peace summit in Switzerland,as he accused Russian President Vladimir Putin of trying to derail the gathering. Zelensky’s appeal came as he locked in a commitment from Belgium to supply 30 F-16 fighter jets by 2028, on the latest leg of a whistle stop tour to rally Western support. Ukraine is pushing to whip up attendance at the peace conference next month where it hopes to win broad international backing for its vision of the terms needed to end Russia’s war. However, the summit risks being overshadowed if Biden, a key supporter of Ukraine, currently engrossed in election campaigning against Donald Trump, opts not to participate, a decision he has yet to indicate.
