Putin Demands from Bulgaria 'Rock-Solid Guarantee' for South Stream

Russian President Vladimir has required a "rock-solid guarantee" that South Stream, if continued, would be carried through.

At a press conference on the occasion of talks with Turkish counterpart Recep Tayyip Erdogan, Putin has made clear the two countries would go on with Turkish Stream gas pipeline, which was announced as an alternative to South Stream at the end of 2014.

"We never politicize issues of economic cooperation," Putin has told the media, amid efforts to renew energy cooperation with Russia from the Bulgarian side.
