There's nothing that could cease the construction of Nord Stream II pipeline at this stage - even the U.S. sanctions. Heiko Maas, the German foreign minister said this as quoted by Deutsche Welle.
'No one will sabotage this project now. The U.S. sanctions may lead to the Western companies, including the German concerns, withdrawing from it. But that, still, would not have it brought to an end. In this case, Russia will have it implemented on its own, and then nothing will affect the gas transit through Ukraine', Maas said, according to DW.
He added that the EU is now negotiating on keeping the Ukrainian gas transit, but these talks could make no sense if the U.S. imposes sanctions, and the Russians will be able to finish the construction works on their own.
The Nord Stream-2 is the project on building a second transit gas pipeline from Russia to Germany in the Baltic Sea. Barack Obama’s administration was against the project. The construction works are to begin in 2018. The project foresees further broadening and modernization of the Nord Stream pipeline. By promoting the Nord Stream-2, Russia aims to refuse from the transit of its gas supplies through the Ukrainian territory.
Nord Stream 2 will have the capacity to transport 55 billion cubic meters of gas per year from Russia to Germany along the bottom of the Baltic Sea.
300 km of the Nord Stream 2 gas pipeline were built in November of 2018. Laying of both lines of the pipeline in the coastal zone of Germany has been completed, and work is being done in the territorial waters and exclusive economic zone of Germany, as well as the exclusive economic zone of Finland.
