Prime Minister Mark Carney and Ukrainian President Volodymyr Zelenskyy spoke by phone Monday, reaffirming their agreement that Ukraine must be a party to any discussions about a possible end to the war in that country.

Touching on Ukrainian anxieties that a direct meeting between Mr. Trump and Putin could marginalize Kyiv and European interests, Zelenskyy said: "Any decisions that are without Ukraine are at the same time decisions against peace. They will not bring anything. These are dead decisions. They will never work."

The upcoming talks between President Donald Trump and Russian President Vladimir Putin comes after Trump recently enforced a deadline for Russia to end its war with Ukraine.
