Now the amendments will move on to be approved by the Council of the EU at the ministerial level.
Commenting on the EU's move, Russian Envoy to the European Union Vladimir Chizhov said that the construction of Nord Stream 2 would still continue.
"Representatives of the Nord Stream 2 concern are showing independence, so I think it can be said with sufficient confidence that construction will continue, and we expect it to be completed in time", Chizhov said on the Rossiya 24 TV channel.
The European Parliament on Thursday approved amendments to the EU Gas Directive, concerning the rules of operation for offshore sections of gas pipelines in the European Union, including the Nord Stream.
Nord Stream 2 is a joint venture of Russian gas giant Gazprom and five European companies. The project envisages the construction of two twin gas pipelines that will run from Russia, through the Baltic Sea and to a hub in Germany. It aims to deliver 55 billion cubic metres (1.9 trillion cubic feet) of Russian natural gas to the EU annually.
