Biden, making his fifth visit to Ukraine as vice president, will arrive in Kiev on Sunday for a three-day visit.
He will meet with Ukrainian President Petro Poroshenko and Prime Minister Arseniy Yatsenyuk and deliver a speech to the country’s parliament.
Biden is the highest-ranking US official to speak before the Ukrainian parliament since former President George H.W. Bush in 1991, during the last days of the former Soviet Union.
Biden’s visit is expected to focus on resolving the conflict in eastern Ukraine even as world leaders have turned their attention to fighting Daesh (ISIL) terrorists, a senior US official said.
The conflict in eastern Ukraine broke out last year following a referendum in the Black Sea peninsula of Crimea, in which people voted overwhelmingly for reunification with Russia.
