"In regard to the issue of sanctions that expire in July, [EU leaders] will discuss this, but I currently don't see any consensus in the [European] Council on this," the EU representative said on the condition of anonymity.
According to the official, "the majority will probably announce that this will be discussed in July."
Speaking at the EC headquarters in Brussels on Wednesday, German Chancellor Angela Merkel warned that a failure to implement the new Minsk agreement will result in further sanctions against Russia.
The Minsk deal refers to an agreement on Ukrainian reconciliation brokered in Belarus in February. The deal stipulates a ceasefire, in force from February 15, and the withdrawal of heavy weaponry by both Kiev forces and eastern Ukraine militia.
Czech President Milos Zeman said last week that there was no reason to slap Moscow with more sanctions since the ceasefire deal was generally holding.
