"You know that the first string of the Nord Stream-2 is already under operating pressure, and the second string will be under operating pressure by the end of this year", Miller said.
He outlined the significance of the Nord Stream 2 as a large project developed by Russia in the face of major international resistance.
On 17 December Nord Stream 2 AG, the pipeline project operator said that it had started filling the pipeline’s second string with gas.

Nord Stream 2 is a joint venture of Gazprom, Royal Dutch Shell, OMV, Engie, Uniper, and Wintershall. The project is designed to carry natural gas from Russia to Germany under the Baltic Sea. The pipeline was completed in September and is now undergoing certification in Germany, which has been stalled by the Federal Network Agency's demand to create a German subsidiary and then file a separate bid therewith.
