Leaders of EU 27 nations aim to reach a political agreement on an oil ban on Monday, an EU official said according to Bloomberg. The official added that there is agreement on the two phases of implementation of the import ban, but that implementation dates remain under discussion. 

The more optimistic (on the chances of a deal being reached) remarks from an EU official comes after more pessimistic remarks from the Estonian PM, who said that it is not realistic to expect an agreement on a sixth package of sanctions against Russia today.
