Ukrainian President Volodymyr Zelenskyy arrived at the Elysee Palace in Paris on Monday for talks with French President Emmanuel Macron on Ukraine peace proposals.

It comes as diplomats face an uphill battle to reconcile Russian and Ukrainian “red lines” as a renewed U.S.-led push to end the war gathers steam, with Ukrainian officials attending talks in the U.S. over the weekend and Washington officials expected in Moscow early this week.

U.S. President Donald Trump's peace plan became public last month, sparking alarm that it was too favorable to Moscow. It was revised some following talks in Geneva between the U.S. and Ukraine a week ago.
