WASHINGTON (AP) Vice President Joe Biden has arrived in Poland on a trip designed to show U.S. resolve against Russia's intervention in neighboring Ukraine.
Biden landed in Warsaw on Tuesday morning. He planned to meet there with Polish Prime Minister Donald Tusk and President Bronislaw Komorowski. He'll also meet with Estonian President Toomas Hendrik Ilves.
The meetings with the NATO allies are part of a broader U.S. campaign to persuade Russian President Vladimir Putin to back off in Ukraine. The U.S. is imposing the most comprehensive sanctions against Russian officials since the Cold War.
Biden will fly later Tuesday to the Baltic nation of Lithuania to meet with President Dalia Grybauskaite and Latvia's president, Andris Berzins.
Poland, Lithuania, Latvia and Estonia share borders with Russia, and Poland borders Ukraine.
