Aiming to guarantee the fuel transport and energy independence in the region, the North-South corridor will focus on natural gas transit and interconnections and will cover the six mentioned eastern countries and possibly Austria. In the longer term, the EC foresees an extension of this integration process to non-EU signatories in the Energy Community Treaty (Albania, Bosnia and Herzegovina, Croatia, Macedonia, Moldova, Montenegro, Serbia and Kosovo).

A declaration signed in February 2010 expresses those countries' joint support for North-South interconnections. The projects involve Croatian and Polish LNG terminals, the Constanta LNG terminal in Romania and other liquefied natural gas and CNG ventures in the wider Black Sea region.

As Sofia News Agency reported, the project is supposed to be formally approved by the European Union by the end of 2011, and to be able to rely on getting EU funding. It is worth adding that its realization will practically make the region of Central and Eastern Europe less vulnerable to a supply cut through the Russia/Ukraine/Belarus route.
