Three years into its life, the SouthStream project entered a period of particular geo-political turbulence as events in Crimea unfolded. In late 2014, with pipe manufacture well under way and the Russian landfall in preparation, President Vladimir Putin cancelled SouthStream.

On 1 December 2014 the project became TurkStream, now making its landfall in Turkey rather than Bulgaria, and with Gazprom taking over all its partners’shares.
