KYIV, Ukraine — Ukraine President Volodymyr Zelenskyy on Sunday welcomed Russia’s offer for direct peace talks, but insisted there must be a full, temporary ceasefire in place before negotiations can start.

French President Emmanuel Macron said on Tuesday he was in favour of imposing new sanctions on Russia in coming days if Moscow failed to agree to a ceasefire, mentioning financial services and oil and gas as possible targets.

European leaders threatened new sanctions unless Moscow accepted a cease-fire right away. President Trump seemed to endorse the idea of a meeting between Ukraine’s and Russia’s presidents, and said he might take part.
