The Biden administration has waived sanctions on a company building a controversial gas pipeline between Russia and Germany.
The US also lifted sanctions on the executive - an ally of Russia's Vladimir Putin - who leads the firm behind the Nord Stream 2 project.The move came in a report on Russian sanctions delivered to Congress by the Department of State.
Critics say the pipeline is a major geopolitical prize for the Kremlin.
The project, which would take gas from the Russian Arctic under the Baltic Sea to Germany, is already more than 95% complete.
The Department of State report notes that Nord Stream 2 AG and its chief executive, Matthias Warnig, a former East German intelligence officer, engaged in sanctionable activity.
President Joe Biden has said he opposes the $11bn (£7.8bn) project. His Secretary of State Anthony Blinken said during his confirmation hearing that he was "determined to do whatever we can to prevent that completion" of Nord Stream 2.
