US President Joe Biden will try to emphasize unity during his visit to Europe this week, according to the White House.

But Biden's aides have never considered Biden visiting Ukraine, and the president remains opposed to sending US troops to that country.

White House press secretary Jen Psaki said that Biden hopes to emphasize cooperation with the West during his visit to Brussels and Warsaw.

“What the [US] President is hoping to achieve is continued coordination and a unified response to the continued escalatory actions of [Russian] President [Vladimir] Putin,” Psaki said at Monday’s press briefing.

Asked about Poland's proposal to deploy an international peacekeeping force in Ukraine, Psaki argued that such a move could run counter to Biden's line.

“Well, we, of course, will continue to work with Poland and other allies and partners in Europe to provide support for the Ukrainian people and help them defend their country against Russian aggression and provide relief to the people of Ukraine.  And we will continue to impose severe consequences. The [US] President—we’ve been—he’s been clear: We’re not going to send American troops to fight Russian troops.  It’s not in the interest of the American people or our national security.  But we’ll continue to discuss a range of ideas, including this one out there,” the White House press secretary said.

A number of Ukrainian leaders have called on Biden to visit Ukraine as part of his trip to Europe. But Psaki said that this option was never considered.

“We have not explored that option,” she said citing the “security considerations” and the "enormous amount of resources on the ground" that will be required for this.
