Bundestag energy committee boss Klaus Ernst said the threat of sanctions over the Nord Stream 2 pipeline project made it appear as if the US saw Germany as a colony. He made the comments at a conference on energy cooperation between Russia and the EU in Berlin on Thursday.

US leaders and officials, including President Donald Trump, Secretary of State Mike Pompeo and ambassador to Germany Richard Grenell, have threatened European companies with sanctions if they continue to take part in the Russian-led Nord Stream 2 gas pipeline project.

"Sanctions here, are not only against Russia, but explicity from the outset, against European [companies], for example against German companies who want to take part in building Nord Stream II," said Ernst.

He went on to describe as "unbearable, the way in which the American ambassador acts in the Federal Republic of Germany."

"One has the impression that we here are now a colony of the US, that's how he acts," said Ernst.

Despite the threat of sanctions, construction of Nord Stream 2 is slated for completion later this year. Among the European entities taking part in the project are companies from Germany, France, the UK, the Netherlands and Austria.
