Berlin has given political support to the building of a new, Dollars 11 billion pipeline to bring Russian gas across the Baltic Sea called Nord Stream 2, despite qualms among other European Union states.
Germany is indeed Russia's biggest export market in Europe for gas, with a dependency that may grow further once Nord Stream 2 is finished.
"Germany is totally controlled by Russian Federation, because they will be getting from 60 to 70 per cent of their energy from Russian Federation and a new pipeline", Trump told Stoltenberg.
Trump is in Brussels to demand that the alliance's European members sharply boost their defense to meet NATO's spending benchmark of 2 percent of gross domestic product.
Over the next few decades, Europe's own gas resources - which accounted for about a third of its supplies in 2016 - are expected to gradually disappear.
Russian Federation has a long history of cutting off access to energy as leverage over Europe and that won't stop, he said.
The two-day meet in Brussels is shaping up as the alliance's most hard in years, with Europe and the U.S. engaged in a bitter trade spat and Mr Trump demanding that North Atlantic Treaty Organisation allies "reimburse" Washington for the cost of defending the continent. The U.S. has long had concerns that Europe is too dependent on Russian gas, and the cash it pays for that fuel helps pay for Russia's military. He later said they discussed Nord Stream 2 but did not give specifics of the conversation.
The gas pipeline will not cross transit countries such as Ukraine, Belarus and Poland, running through the exclusive economic zones and territorial waters of Russia, Finland, Sweden, Denmark and Germany.
What does the future hold for Nord Stream 2? That said, the works have been scheduled in close co-ordination with Nord Stream AG's upstream and downstream partners so that gas supply to European customers during that period is ensured via the alternative transportation route. The plans were drawn up at a time when Russian Federation appeared eager to engage with the West - and many Germans still see Russian Federation more positively than other countries do.
"I am very glad that we are united today in freedom as the Federal Republic of Germany and that we can therefore also make our own independent policies and make our own independent decisions".
Buechele also said that to claim Russian Federation would be able to control gas markets was "factually wrong and politically absurd".
Trump didn't identify Nord Stream 2 by name.
