A pipeline project between Russian Federation and Germany risks triggering US sanctions because of security concerns, a senior American diplomat said Thursday.
"That means that any pipeline project, and there are multiple pipeline projects in the world that are potentially covered, is at an elevated sanctions risk", Bloomberg cited Oudkirk as saying.
The US push came a day before Chancellor Angela Merkel travels to Sochi to meet Russian President Vladimir Putin for talks that will touch on Nord Stream 2, as well as the US decision to withdraw from the Iran nuclear deal.
Earlier, Us officials said that the United Stats may impose sanctions on the companies involved in the implementation of the Nord Stream 2 project.
Note that the U.S. and the countries of Eastern Europe are opposed to the construction of the Nord stream - 2, and believe that its implementation will lead to an actual degradation of the Ukrainian gas transportation system and the strengthening of the Russian Federation in the gas market of the EU.
Altmaier has said he is optimistic that a "substantial" amount of gas will flow through Ukraine in the future. Up to now Turkey received Russian gas transited via Ukraine, Romania and Bulgaria.
Oudkirk rejected suggestions that Washington is opposing the pipeline to help USA liquefied natural gas exports.
"Does he agree that there appears to be no economic justification for this, but it is instead a political project created to increase European dependence on Russian gas and to weaken Ukraine and will he press that point on our allies, particularly Germany and Denmark?"
It added the national permitting procedures in the other three countries along the route - Russia, Sweden and Denmark - are "proceeding as planned".
Denmark is considering passing a law that could block a disputed Russian pipeline project which would run through the North Atlantic Treaty Organisation member's territory due to security concerns.
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".
