Pro-European chocolate billionaire Petro Poroshenko was sworn into office Saturday as Ukraine's fifth president.
In his inaugural address, lasting less than an hour, Poroshenko mapped out a peace plan to resolve unrest in the conflict-torn eastern region.
The vice president's office reports that while attending the inauguration, Biden spoke with Canadian Prime Minister Stephen Harper about supporting a democratic, united Ukraine, according to a White House pool report.
Poroshenko won 54.7 percent of the vote in elections late last month.
