The Polish antitrust regulator announced that they are fining Gazprom for refusing to cooperate in a case related to the construction of Nord Stream 2.

The fine amounts to 50 million euros and is the largest possible, explained the Polish side.

The investigation is related to the financing of the pipeline. The regulator asked the Russian company for documents related to its construction, but they did not provide them.

The case dates back to 2018, and in addition to Gazprom, it concerns one Swiss and four Dutch companies, according to Novinite and bnt.

Nord Stream 2 is to deliver gas from Russia to Germany via the Baltic Sea. A number of countries have spoken out against the project, including Poland, which says it will strengthen Russia’s monopoly on the European gas market. Gazprom said it could complete the construction of the pipeline on its own.
