Earlier, Sandra Oudkirk, US deputy assistant secretary of state for energy, has declared that the White House is willing to impose economic sanctions against the Nord Stream 2 pipeline project, according to Spiegel Online.
The Thirsk and Malton MP said: "Despite the fact oil and gas exports make up 70% of Russia's worldwide trade, these are not now covered under the European Union sanction regime due to the high reliance of the European Union on Russian gas exports".
"Any pipeline project - and there are many multiple pipeline projects in the world that are potentially covered by this sanctions authority - is in an elevated position of sanctions risk", Oudkirk said.
Mr Johnson responded: "I can assure him that we in the UK Government are well aware of the deep controversy surrounding Nord Stream 2 and we raise it not just in Ukraine but of course with our European friends and partners".
German Chancellor Angela Merkel said that Germany regards the Nord Stream 2 gas pipeline as a safe economic project for Europe.

"Germany hooks up a pipeline into Russian Federation, where Germany is going to be paying billions of dollars for energy into Russian Federation. But shale gas is much more expensive than Russian gas, so lock the Nord stream-2 itself does not guarantee exports", said Altmaier.
"The new project would permit new technologies to be placed along the pipeline route, and that is a threat", she said.
Oudkirk rejected suggestions that Washington is opposing the pipeline to help U.S. liquefied natural gas exports.
Until now, however, Germany does not seem to succumb to the pressures and opposes the other side with the slogan "America First", arguing that, in this case, Europe should also look at its own interest, especially when Russian gas is cheaper than the American shale gas.
In the German Lubmin began the construction of a gas receiving station within the project of the pipeline "Nord stream-2".
Denmark must still rule on whether the pipeline can be built near its coast, and other routine permissioning processes are still under way in Sweden and Russian Federation.
