U.S. President Donald Trump and Ukrainian leader Volodymyr Zelensky will attend the International Economic Forum in Davos.
The Trump's visit has been announced by White House spokeswoman Stephanie Grisham.
This trip outside the United States will be the first one for Trump after the impeachment announcement and the elimination of Iranian General Qassem Soleimani.
Last year, Trump did not visit Davos due to the government shutdown.
At the same time, Zalensky's visit to the event was announced by Viktoria Kaleniuk, Executive Director of NGO Center for Combating Corruption.
Viktor Pinchuk, Vadym Novinsky, DTEK representative Maksym Timchenko, and Foreign Minister Vadym Prystaiko are also among attendees.
A total of 66 delegates are registered from Russia, including notorious oligarch Oleg Deripaska.
