"We will go forward with the implementation of the project, and Europe knows it," Dimitris Velanis told RIA Novosti.
"We support the supply of energy resources from all sources, but sources in Russia cannot be excluded from this process. That is our position," the adviser stressed.
"Let the parties compete with each other and let those win, which are more profitable for economy. I think only economy will finally settle this dispute," Dimitris Velanis told RIA Novosti.
Russian Deputy Prime Minister Arkady Dvorkovich met with Greek Prime Minister Tsipras on Saturday to discuss the prospective construction project.
Greece will support the Burgas-Alexandroupoli pipeline project stretching from the Black Sea to the Aegean if the talks on the issue would be renewed, he said.
"[Bulgaria] stopped a perfect Burgas-Alexandroupoli oil pumping project, [with a capacity] from 30 to 50 million tonnes per year. That could have eased the situation in the transportation of oil in the southern part of the Mediterranean Sea. It was stopped abruptly and it is possible to say, on political grounds. This project once again is being discussed by different parties, and we will support this project."
