“It is very embarrassing that Germany's sovereign right to make decisions regarding its own energy supply is, in principle, being discussed at the international level,” he said.

As the specialist noted, the US authorities, for example, prohibit any intervention of other countries when it comes to the United States.

“When we observe today that, for example, Poland does not approve of the signed EU treaties and violates these treaties, but at the same time considers itself entitled to interfere in German policy regarding Nord Stream 2, we are faced with a violation of international political conventions regarding this project, ”said Helmeier.

The economist added that he considers it necessary to actually protect the sovereignty and interests of Germany, as this is of fundamental importance.

“The fact remains that Russia - it does not matter: during the Soviet era or now - did not in the least violate the agreements on energy supply.

On the other hand, the fact also remains that Ukraine threatened us.

Namely, she threatened to interrupt the transmission, transit of gas, that is, she acted as blackmail, ”he concluded.

Earlier, US Undersecretary of State for European and Eurasian Affairs Victoria Nuland said that the United States had reached an agreement with Germany on Nord Stream 2.

Later, German Foreign Minister Heiko Maas commented on the agreements between Germany and the United States on the gas pipeline.
