The Kremlin said on Wednesday that U.S. sanctions targeting the Russia-led Nord Stream 2 gas pipeline project were unfriendly and destructive.
The State Department said on Tuesday that Secretary of State Mike Pompeo would submit a report to Congress on sanctions against vessels engaged in pipe-laying for Nord Stream 2.
Construction of the 1,230-km Nord Stream 2 pipeline to Germany is almost complete, barring a roughly 120 km final stretch in Danish waters.
Work stopped in December after pipe-laying company Swiss-Dutch Allseas suspended operations because of U.S. sanctions targeting companies providing vessels.
