Leaders of the 28 EU countries, meeting yesterday in Brussels, said they expect Russia to cooperate with newly elected President Petro Poroshenko, winner of Sunday's elections.
In a statement, the EU heads of state and government said Moscow should "use its leverage on the armed separatists to de-escalate the situation in eastern Ukraine."
The European leaders said that as a priority, the Russian government should prevent separatists and weapons from crossing the border into Ukraine.
