A summit between European Union officials and Ukraine's leaders is scheduled to be held in Kyiv at the end of April.
A statement on Ukrainian President Petro Poroshenko's official website said that during a Saturday phone conversation with European Commission President Jean-Claude Juncker, "the parties have agreed ... that the Summit Ukraine-EU would be held on April 27."
The statement also said that while Juncker had planned to be in Kyiv on Monday to jointly chair a cabinet meeting with Poroshenko, he had to cancel the trip "due to unforeseen health conditions."
The April summit is expected to address Ukraine’s request for European peacekeepers to help monitor the cease-fire between Kyiv and pro-Russian separatists. Help for the country’s struggling economy is also on the agenda.
The European Parliament on Wednesday approved economic aid of about $2 billion for Ukraine as part of an International Monetary Fund program of nearly $40 billion. Two-thirds of the new aid could be disbursed by the end of 2015.
The EU and the United States have imposed economic sanctions on Russia that will stay in place until there is clear evidence that the cease-fire brokered in mid-February by the French president and German chancellor is being respected.
The West has accused Russia of aiding pro-Russian forces in eastern Ukraine, an accusation that Moscow has continuously denied.
Since fighting broke out in April of last year, more than 6,000 people have been killed.
