The European Commission has violated the provisions of the association agreement with Ukraine when making decision on the OPAL pipeline, the Foreign Ministry of Ukraine has stated.

"The approval of such decisions without prior consultations with Ukraine is the breach of Article 274 of the association agreement between Ukraine and the EU, which provides for mutual consideration by the parties of the capacity of energy infrastructure of both sides, as well as holding consultations and coordination of actions in the field of security of energy resources supply," the ministry's press service said, with reference to Deputy Foreign Minister of Ukraine for European Integration Olena Zerkal.

According to the press service, Zerkal voiced the appropriate position to Head of the EU Delegation to Ukraine Hugues Mingarelli at a meeting on November 9.

In addition, she said the European Commission, when preparing decisions on OPAL, had to adhere to the commitments undertaken within the Energy Community. In particular, the matter concerns the obligation to adhere to the principle of solidarity in relations with other members of the community (including Ukraine) and avoid making decisions contrary to EU competition law.
