"We continue to work with Poland and other likeminded European allies and partners to stop Russia’s proposed Nord Stream 2 pipeline, which would undermine European energy and national security while also hurting Ukraine," said Pompeo.

He added that the U.S. shares the view that the Nord Stream 2 project "does not contribute to energy security of Europe."

"We consider it to be an undertaking that is mismatched or actually detrimental to the energy security on the old continent," the U.S. Secretary of State said.
