Vice President Joe Biden spoke with Ukrainian Prime Minister Arseniy Yatsenyuk Friday to welcome progress in Ukraine.
Biden congratulated Yatsenyuk on reaching a preliminary agreement with the International Monetary Fund to stabilize and grow the country's economy, according to a White House pool read out.
On Thursday, President Obama signed legislation passed by Congress to provide economic assistance to Ukraine as well as sanctions against Russia for annexing the Crimean peninsula.
During the call, the vice president also reaffirmed the importance of improving Ukraine’s energy security and vowed to work closely with other European countries to ensure energy isn't being used as a political weapon.
He closed talks by welcoming preparations for free and fair presidential elections in Ukraine on May 25.
