Ukrainian President Volodymyr Zelenskyy is due to address world leaders gathered in Davos, Switzerland, for the World Economic Forum (WEF), APA reports citing BBC.
No Russian officials or companies will be present at the international gathering of political and industrial leaders.
But a Ukrainian delegation, including the foreign minister, has made the journey.
"The major request to the whole world here is: do not stop backing Ukraine," Ukrainian MP Ivanna Klympush-Tsintsadze told reporters on the eve of the summit.
The summit has not been held since January 2020 because of the coronavirus pandemic. A virtual forum took place last year, with Russian President Vladimir Putin among the speakers.
