He stated this in an interview with Bild.
Lamsdorf linked his position to the murder of Georgian citizen Zelimkhan Khangoshvili in Berlin in 2019. German authorities claim that the murder was committed "on behalf of Russian government agencies."
“I believe that this murder here in Berlin, really in the very heart of our capital, a few hundred meters from government buildings, is such a serious attack on German sovereignty that we should think three times whether we can actually lay this pipeline,” said the deputy.
He called for the cancellation of the project and added that "Russian policy is unfriendly towards Germany and unfriendly towards the European Union."
As the Russian ambassador to Germany Sergey Nechaev stated earlier, the German side’s statement about the involvement of Russian structures in the murder "is not supported by any facts and evidence."
At the end of August 2019, a Russian was arrested in Germany on suspicion of the murder of a Georgian citizen.
Later, spokesman for the Russian leader Dmitry Peskov said that assumptions about Russia's involvement in the contract killings in Berlin are completely groundless.
