The proposed Sava pipeline would extend 480 km along the Sava River to Banja Luka to link the Serb Republic, which together with the Muslim-Croat federation makes up Bosnia, to a section of the South Stream gas pipeline currently being considered by Srbijagas and Russia's Gazprom.

Slavija Internacional is hoping to obtain Srbijagas as an investor in the pipeline, which would have a capacity of 1.2 Bcm, before the end of the year.
