The operator of the operational Nord Stream 1 undersea gas pipeline from Russia to Germany said that transportation of natural gas to Europe was continuing normally.
"Nord Stream AG is not involved in the Nord Stream 2 project and not engaged in the activities of Nord Stream 2 AG. Nord Stream AG is, therefore, not targeted by the sanctions against Nord Stream 2 AG neither by any other sanctions," it said in a statement.
"Consequently, Nord Stream AG is able to execute its payments and settlements."
Nord Stream is a system of offshore natural gas pipelines in Europe, running under the Baltic Sea from Russia to Germany.
It includes two pipelines running from Vyborg in north western Russia to Lubmin, near Greifswald, in north eastern Germany forming the original Nord Stream.
In Lubmin Nord Stream 1 is connected to the OPAL pipeline to Olbernhau in eastern Germany, on the Czech border, and to the NEL pipeline to Rehden, near Bremen, in north western Germany.
Nord Stream 1 is owned and operated by Nord Stream AG, whose majority shareholder is the Russian state company Gazprom.
Nord Stream 2 is owned and planned to be operated by Nord Stream 2 AG, which is a wholly owned subsidiary of Gazprom. However, this has ceased operations following the outbreak of war in Ukraine.
The first line of Nord Stream 1 was laid by May 2011 and was inaugurated on 8 November 2011.
At 1,222 km (759 miles) in length, Nord Stream 1 is the longest sub-sea pipeline in the world.
