A decision to drop Nord Stream 2 “should be on the mind of the rooster” for Germany, whose politicians have already acknowledged that this is a political project, Morawiecki told Bloomberg TV.

Warsaw has long opposed the Nord Stream 2 project, which would allow 55 billion cubic meters of natural gas to be transported each year from Russia to Germany via the Baltic Sea platform, bypassing transit countries such as Poland and Ukraine.

Poland sees Nord Stream 2 as a purely political move that would increase Europe’s dependence on Russian natural gas and allow Russia to put pressure on transit countries.

The project would be especially dangerous for Ukraine, which could be disconnected from the transit of natural gas.

Construction of the Nord Stream 2 pipeline is almost complete.

On Monday, the German chancellor’s spokeswoman said that Angela Merkel does not rule out a measure regarding the Nord Stream 2 project in response to the poisoning of Aleksei Navalny. The Russian government denies any responsibility in this case.

The United States has imposed sanctions on companies involved in Nord Stream 2, and several lawmakers have warned that other measures will follow.

Russia’s foreign ministry announced on Tuesday that it had summoned the German ambassador to Moscow in connection with statements made by Berlin authorities about the condition of Russian opposition politician Aleksei Navalny, according to Reuters.

Navalny, 44, a prominent critic of Russian President Vladimir Putin, was flown to Germany last month after being injured during a flight from Tomsk, Siberia, to Moscow. After a series of tests, Germany came to the conclusion that the Russian opponent had been poisoned with a Noviciok-class neurotoxic agent.

Russian diplomacy spokeswoman Maria Zaharova accused Germany of “bluffing” in a statement on its Facebook page.

Charite Hospital in Berlin, where Navalny is being admitted, announced Monday that he has been removed from an induced coma and that his health is improving.
