Ukrainian President Petro Poroshenko will meet with U.S. Vice President Joe Biden for a working lunch on March 31, the White House announced on March 30.
Poroshenko is one of more than 50 leaders from countries around the world in Washington this week for President Barack Obama's fourth and final Nuclear Security Summit.
Poroshenko had sought a meeting with Obama, but apparently was unable to arrange one because of Obama's full schedule.
Ukrainian Deputy Foreign Minister Vadym Prystaiko said on March 29 that Poroshenko wanted to meet with Obama because Ukraine "has been at the cutting edge of the fight between democracy and what we abandoned in the past and deserves this meeting."
