Editor's Note : Stratfor closely monitors the ebbs and flows of world energy. Aside from production, the transportation of crude oil, natural gas and petroleum products is of paramount concern for oil-producing nations. For energy consumers, transit routes are indispensible lifelines. A huge amount of the world's energy is transited through pipelines, across the Eurasian landmass in particular. In this periodic series we will examine some of the most geopolitically significant pipelines running through Europe and Asia. In this installment, Stratfor examines TurkStream, the successor to South Stream, from the Turkish perspective. Europe and Russia continue to spar for political influence in Eurasia in the latest battle over Russia's TurkStream pipeline project, formerly known as Turkish Stream.
