The news came after the Reuters news agency reported on Tuesday that the Nord Stream 2 AG company, based in the Swiss city of Zug, was considering filing for insolvency as it attempted to settle claims ahead of a US sanction deadline for other entities to stop dealings with it.
US President Joe Biden said last week that the United States would impose sanctions on the company in charge of building Russia's Nord Stream 2 gas pipeline to Europe by targeting the firm and its corporate officers.
Germany last week halted the certification of the undersea pipeline.
The German move, announced by Chancellor Olaf Scholz, came after US officials were cited as saying in December that Washington had an understanding with Berlin about shutting down the controversial pipeline if Russia invaded Ukraine.
A Polish security official warned last year that the Nord Stream 2 pipeline would give Russia "a chance to destabilize NATO."
Poland has strongly criticized the Nord Stream 2 project, which is almost complete, amid concerns that it could make the European Union more dependent on Russian gas.
Polish lawmakers last year passed a motion calling on EU and NATO countries to take action to stop the construction of the pipeline.
The motion warned that the gas link would open the way for Russia to mount an armed attack on Ukraine.
Russia’s President Vladimir Putin last Thursday announced a "special military operation" against Ukraine to eliminate what he said was a "serious threat" against his country.
Despite appeals and warnings from the international community, Russia launched a full-scale invasion of its southern neighbour by land, air and sea, the biggest attack by one state against another in Europe since World War II, the Reuters news agency reported.
Top Polish officials have condemned Russia's attack on Ukraine and vowed to support the Ukrainian people.
