Without trade settlement Europe since June 1, will face US duties on imported steel and aluminum.
The U.S. president in March imposed tariffs of 25 percent on steel and 10 percent on aluminum imports but gave European Union countries until June 1 to negotiate new deals with the U.S.
According to sources, the position of the tramp due to a desire to force Russia out of the gas market in favor of its own supplies of liquefied natural gas, as well as wanting to maintain Ukraine's status as a major transit country for Russian gas to Europe.
In early April, after meeting with the leaders of Latvia, Lithuania and Estonia at the White House, Trump criticized the Nord Stream 2 pipeline.
Despite taking a hard line against Russian Federation in recent years over its aggression in Ukraine and other matters, Merkel has defended the pipeline project, saying Germany badly needs to secure its gas supplies. In addition, the foreign Ministry explained why the "Nord stream-2" favorable to Germany.
Opponents of the project - including Poland, the Baltic States, Ukraine, Moldova, USA and Denmark argue that the "Nord stream-2" will increase the EU's dependence on Gazprom, which already supplies about a third of the volume of gas in the EU. The only shareholder of the latter is Gazprom.
Oudkirk said the project raises security concerns because it would divert gas flows away from Ukraine, which depends heavily on transit fees, and could become a pathway for Russian Federation to install high-tech monitoring and listening equipment in the Baltic Sea, a sensitive military region.
He said Germany viewed Nord Stream 2 as primarily a commercial project, but saw the need to consider the interests of Ukraine as a gas transit country, and of countries in Central and Eastern Europe.
Nord Stream said Germany and Finland have granted all the necessary permits for the construction and operation of the pipeline.
The United States also opposes the Turkish Stream offshore pipeline that would bring Russian gas via the Black Sea to Turkey for the same reasons, she said. In this regard, Russian Federation was forced to develop an alternative route around the country.
