Nord Stream 2 AG, a Swiss-based firm behind the construction of the Nord Stream-2 gas pipeline, has laid about 250 kilometres of pipes, company spokesman Jens Mueller said.
"As of now, the company built about 250 km of the pipeline," Sputnik cited Mueller as saying.
The project continues in spite of the strong opposition from the U.S.
Nord Stream 2 is a joint venture of Gazprom and five European companies. It aims to deliver 55 billion cubic meters of Russian natural gas annually to the European Union across the Baltic Sea to Germany. The pipeline project has been welcomed by some countries in Europe and opposed by others, fearing that it might increase their dependence on Russian gas.
