US president Joe Biden will travel to Poland this week to discuss international efforts to support Ukraine and "impose severe and unprecedented costs on Russia for its invasion, the White House has said.
The discussions will follow Biden's meetings in Brussels, Belgium with NATO allies, G7 leaders, and European Union leaders.
A White House press statement reads:
"On Friday, March 25th, President Biden will travel to Warsaw, Poland, where he will hold a bilateral meeting with president Andrzej Duda. The president will discuss how the United States, alongside our allies and partners, is responding to the humanitarian and human rights crisis that Russia's unjustified and unprovoked war on Ukraine has created."
Ahead of Friday's meeting, Biden will also hold a call with French president Emmanuel Macron, German chancellor Olaf Scholz, Italian prime minister Mario Draghi, and UK prime minister Boris Johnson on Monday.
On Thursday he will attend a summit of NATO leaders, who will use the meeting to look at strengthening the bloc's own deterrence and defence, immediately and in the long term, to deal with the now openly confrontational Putin.
That gathering is intended not just to show NATO's "support to Ukraine, but also our readiness to protect and defend all Nato allies," NATO secretary-general Jens Stoltenberg told CBS' Face the Nation on Sunday.
"And by sending that message, we are preventing an escalation of the conflict to a full-fledged war between NATO and Russia," Stoltenberg said.
