Wintershall Dea, Europe's leading independent gas and oil company, has said it has no plans to further fund the construction of Russia's Nord Stream 2 gas pipeline.

That is according to the company's 2020 annual report.

In particular, the company's top managers are concerned about "an aggressive approach toward the contractors of the project" on the part of the United States, which has tightened sanctions against Nord Stream 2.

"The company's loan payments to Nord Stream 2 AG amount to EUR 730 million and were completed prior to the revision of the 'Countering America's Adversaries Through Sanctions Act 'CAATSA' Section 232 Public Guidance' of the US Department of State," the report said.

The Nord Stream 2 project envisages the construction and operation of two gas pipeline branches with a total throughput capacity of 55 billion cubic meters of natural gas per year from the coast of Russia through the Baltic Sea to Germany. It should connect Russia's Ust-Lug and Germany's Greifswald. This new pipeline bypassing Ukraine is to be built next to the existing Nord Stream 1 pipeline.

The construction was expected to be completed before the end of 2019.

The pipeline will be 1,220 km long. The project is being implemented by Russia's Gazprom in alliance with European companies. Ukraine stands against the construction of Nord Stream 2 as it will most likely lose its status of a gas transit country, while its potential revenue losses are estimated at US$3 billion annually. The project is also highly criticized by the U.S., Poland, and the Baltic States.

On November 4, 2020, the media reported that U.S. Congress wanted to expand sanctions against Nord Stream 2 and TurkStream.

The United States is urging European allies and private companies to halt works on Nord Stream 2, and is preparing broader sanctions against the Russian project in the coming weeks.

The U.S. Senate approved the U.S. defense budget for the fiscal year 2021, which provides for new sanctions against Russia's Nord Stream 2.

On January 7, 2021, a fund was established in Germany to support the completion of the Nord Stream 2 project.

On January 13, 2021, the U.S. Department of State notified European companies involved in the construction of Nord Stream 2 of the risk of imposing new sanctions.

On February 22, the United States made changes to the Specially Designated Nationals (SDN) List of the Office of Foreign Assets Control (OFAC) by including a Russian-flagged vessel Fortuna involved in the construction of the Nord Stream 2 gas pipeline.

As of February 23, 2021, at least 18 European companies had either terminated their participation in the Nord Stream 2 pipeline or had pledged to withdraw from the project over threats of U.S. sanctions, according to a U.S. State Department report for Congress.
