"We have have already started work on an intergovernmental agreement," Miller told reporters.
"It does not include talks on concrete details concerning the capacity of the pipeline or schedules for the project implementation, but the work on the text of the agreement in underway, and it is not influenced by any factors," Miller stressed, answering the question about a possible impact of the current political situation, including the Syrian crisis, on the project.
Russian Energy Minister Alexander Novak earlier said that the intergovernmental agreement on the Turkish Stream gas pipeline could be signed in the beginning of 2016.
The Turkish Stream is a proposed gas pipeline with an annual capacity of 63 billion cubic meters, running from Russia to Turkey beneath the Black Sea. The pipeline is expected to continue to a hub on the Turkish-Greek border, from where it could be extended to southern Europe.
