Russian Energy Minister Alexander Novak has told EU official Maros Sefcovic that Moscow will no longer pursue the South Stream project, the Commission says.
In a statement the European Commission explains Novak held a phone conversation with Sefcovic, who is Vice President for Energy Union, on Thursday.
The two discussed "the Russian plans as regards the South Stream project."
Brussels and EU member states have been awaiting a formal notice about the end of South Stream, but maintain they have received no written document confirming this.
Sefcovic has said that the Commission is to "intensify" its work with member states in Central Eastern Europe and Southeast Europe "on the interconnection of the European markets and diversification of gas supplies."
