Moscow pledged retaliatory measures after a new set of sanctions imposed by the United States on a Russian ship and two companies involved in the Nord Stream 2 gas pipeline, Russia’s foreign ministry said in a statement on Saturday.

However, opponents of the project said that the sanctions were insufficient to block the project, which is very near completion.

“We view such hostile actions by the Biden administration as dictated by a lack of political will and an unwillingness to build U.S.-Russian relations on a partnership basis,” Maria Zakharova, a spokeswoman for Russia’s Foreign Ministry, was quoted as saying in the statement.

The $11 billion project, which will double the existing Nord Stream pipeline across the Baltic Sea and allow Russia to bypass Ukraine when piping gas to Europe, has been a focal point of tensions between Moscow and Washington.

The Biden administration on Friday slapped sanctions on a Russian ship and two companies involved in the Nord Stream 2 gas pipeline.

The sanctions were imposed on ship Ostap Sheremeta, ship owner JSC Nobility and construction company Konstanta, the State Department said in a report to congressional committees. A copy of the report was seen by Reuters.

US President Joe Biden separately issued an executive order allowing for sanctions to be imposed on certain Russian pipelines.

The United States and Britain also imposed sanctions on Friday on men they said were Russian intelligence operatives responsible for the poisoning one year ago of Kremlin critic Alexei Navalny.

Washington separately imposed sanctions on another two men and four Russian institutes it said were involved in chemical weapons research or what it described as an assassination attempt against Navalny.

Navalny was flown to Germany for medical treatment after being poisoned in Siberia on Aug. 20 last year with what Western experts concluded was the military nerve agent Novichok.

Moscow has rejected their findings and accused the West of a smear campaign against it.
