The parties agreed to develop last year&#39;s trilateral memorandum between Ukraine, Poland and the United States on cooperation in the energy sector to diversify sources of energy supplies. The United States is also convinced that the Russian project threatens transatlantic security. Last week, the U.S. Senate approved a bill to sanction Nord Stream 2. It was accepted by a majority vote. As soon as Congress agrees on the final version of the document, it will be sent to President Donald Trump for signing. The Nord Stream 2 gas pipeline, which is being laid along the Baltic Sea seabed towards Germany, costs US$11 billion and is 90% complete. The unfinished part must be completed in the territorial waters of Denmark.
