Bulgarian Prime Minister Boyko Borissov revealed his country too had plans to bring Russian gas to its borders - just like Germany, which plans an expansion of the Nord Stream pipeline, EurActiv's Georgi Gotev writes.
Nord Stream 2, a project to increase the capacity of an existing offshore pipeline under the Baltic Sea, is expected to be a highly divisive issue at the summit.
At least seven countries from Central Europe have taken the position that Russia's plans to double the capacity of its Nord Stream gas pipeline to Germany run counter to EU interests and risk further destabilizing Ukraine.
But this did not deter the Bulgarian prime minister from making plain that his country has the ambition to build a southern arm, similar to Nord Stream, bringing Russian gas to the Bulgarian shores.
Borissov said Bulgaria will have a gas hub named "Balkan" which will collect gas from the country's own production, gas brought through the Greece-Bulgaria interconnector (IGB), Azeri gas in the future from the Southern Gas Corridor (SCG), but also Russian gas.
