The energy project could be completed in September, according to the agency, which also cites analysts.
"Berlin is trying to buy time and guarantee the completion of construction, because, in their opinion, when the project is completed, everything will look different (for the United States)," - said an unnamed source.
According to the second source, the German authorities believe that there are still people in Washington who want to conduct a dialogue on Nord Stream 2 and find a solution.
Earlier, the head of the Bundestag Committee on Economics and Energy, Klaus Ernst, urged not to discuss with the United States the "mechanism for stopping" the construction of the gas pipeline.
Also, the Minister of Energy and Economy of the Federal Republic of Germany Peter Altmeier said that he considers it wrong to constantly raise new questions about Nord Stream 2.
As noted by the head of the German Foreign Ministry, Heiko Maas, the main priority of the FRG government at the present time is to create conditions for the completion of the construction of the pipeline.
