Top European and Ukrainian envoys have met in Geneva ahead of talks with U.S. Secretary of State Marco Rubio about President Donald Trump's proposal to end Russia’s war on Ukraine.

By Anastasiia Kozlova and Purvi Agarwal (Reuters) -European shares inched lower on Friday, but were poised for their fifth consecutive month of gains, as rising bets of a U.S. interest rate cut and some progress on a Russia-Ukraine ceasefire lifted investor sentiment this week.

European Union lawmakers have voted to deepen integration of the bloc’s defense industry with Ukraine as a U.S. peace plan remains in flux and Russia’s unconventional warfare operations rattle the 27-nation bloc.

Ukrainian, American and European officials gathered in Geneva on Nov. 23 to discuss a draft plan presented by Washington to end the war in Ukraine.
