President Obama will visit Poland and other European countries in June, Vice President Biden announced Wednesday.
Obama will be there for the country's 25th anniversary of its first Democratic elections in 1989 after the fall of the Soviet Union. He last visited Poland, a NATO ally, in 2011.
Press secretary Jay Carney said the participating countries would discuss "broad shared economic, security and development issues" as well as the situation in Ukraine.
Obama is then expected to attend a ceremony marking the 70th anniversary of D-Day in Normandy. He marked the 65th anniversary of the landing there in 2009.
Biden made the announcement during a speech at the Atlantic Council's tribute to NATO and the European Union. He visited Poland last month and Ukraine a week ago.
The vice president reassured NATO allies that "there are no ifs ands or buts about" the U.S. commitment to Article 5, which holds that nations will defend any ally that is attacked. He noted that the United States has stepped up its military presence in the Baltic region and the Black Sea.
"That is an absolute ironclad guarantee," he said.
Biden said Russia must respect international order or continue to face further costs and isolation.
“If Russia wants to benefit from the international order it has to respect that order and abide by the rules otherwise it is going to face growing cost and growing isolation,” he said.
He noted a strong, uncorrupt Ukraine would be the "most significant bulwark against Russian aggression." The country is slated for presidential elections next month.
The administration on Monday issued a new round of sanctions against Russian officials and businesses linked to Russian President Vladimir Putin. Monday's sanctions, along with European allies, were the latest penalty since Russia's annexation of Crimea last month. Since then, the United States and other world leaders have called on Russia to pull back troops from the eastern border of the country and to publicly call for pro-Russian separatists to leave occupied Ukrainian government buildings.
Biden praised the expansion of NATO 15 years ago to include a number of Baltic states and said its expansion had nothing to do with Russia's current aggression. Ukraine is not a NATO member but it borders countries allied with the organization.
He said the United States continues to reject the notion of a sphere of Russian influence in the region.
"It was borne in the Kremlin," Biden said of the current crisis in the region. "It was born in Putin's mind. It has nothing to do with the fact that we expanded NATO."
