"The most important thing today, one of the key issues, is to ensure the safety of supplies. That is why, realizing that such situations may arise in the future, Russia has long set the task of diversifying supplies of our energy. To this end, we launched the plan to build the North-Western pipeline system under the Baltic Sea and another system under the Black Sea (we tentatively call it the South Stream). For that purpose, we built the Blue Stream pipeline to Turkey on the bottom of the Black Sea."
