The Commission seeks to ensure that, if built, Nord Stream 2 operates in a transparent and non-discriminatory way with an appropriate degree of regulatory oversight, in line with key principles of international and EU energy law, reads the statement.

The Vice-President for Energy Union Maros Sefcovic said: "Creating a well-diversified and competitive gas market is a priority of the EU's energy security and Energy Union strategy. As we have stated already several times, Nord Stream 2 does not contribute to the Energy Union's objectives. If the pipeline is nevertheless built, the least we have to do is to make sure that it will be operated in a transparent manner and in line with the main EU energy market rules."

On signed a shareholders' agreement on a joint project company, which would be engaged in the construction of the Nord Stream 2 gas pipeline.

According to Naftogaz CEO Andriy Kobolev, the pipeline in no way contributes to the diversification of gas supplies to the EU and does not provide the European Union with access to new sources of gas. Moreover, the implementation of the Nord Stream 2 project will lead to the fact that the entry points of Russian gas supply into the EU will be almost entirely concentrated in Germany. However, the existing gas pipelines between the north of Germany and the countries of Central and Eastern Europe do not have enough capacity to deliver the necessary volumes of gas to the eastern European regions.
