Speaking in a video message Sunday, President Volodymyr Zelenskyy named Warsaw, Bratislava, Istanbul, Budapest or Baku as alternative venues.
He said other locations are also possible but made clear that Ukraine doesn't accept Russia's selection of Belarus.
The Kremlin said Sunday that a Russian delegation had arrived in the Belarusian city of Homel for talks with Ukrainian officials.
Kremlin spokesman Dmitry Peskov said the delegation includes military officials and diplomats.
