Vice President Joe Biden is heading for Poland and Lithuania next week to discuss the Russian incursion in Ukraine, the White House said Friday.

Biden will go to Warsaw, then to Vilnius, Lithuania, where he will meet with the presidents of the Baltic republics of Estonia, Latvia and Lithuania. In both places, the topic will be the Ukraine crisis and United States’ support for its NATO partners.

Earlier Friday, Secretary of State John Kerry said in London that the U.S. would not recognize the outcome of the referendum scheduled for Sunday in Ukraine’s Crimea region. He said that would amount to an “annexation of Crimea” by Moscow – voters in that region are widely expected to choose to join Russia.

Since sending forces into Crimea two weeks ago, Russian President Vladimir Putin has mobilized thousands of troops near the border with eastern Ukraine.
