U.S. President Joe Biden will travel to Poland on Friday to meet with President Andrzej Duda for discussions over Ukraine, the White House said Sunday.

In a statement, White House Press Secretary Jen Psaki said that Biden's trip will come after a visit to Belgium to meet with leaders from NATO, the G7 and the European Union.

"But there are no plans to travel into Ukraine," she added.

Polish Prime Minister Mateusz Morawiecki, along with the Czech and Slovenian prime ministers, went to Kyiv last week.

U.S. Vice President Kamala Harris also met with Duda in Warsaw earlier this month, with both condemning Russia's military action.

That meeting came shortly after the United States rejected a Polish offer to send MiG-29 fighter jets to Ukraine via a U.S. air base – an offer which caught U.S. officials off guard – saying the proposal raised "serious concerns" for the entire NATO alliance.

The United Nations has estimated around 10 million Ukrainians have fled their homes, with roughly one-third of them going abroad, mostly to Poland.
