As reported by Censor.NET citing Interfax, Poroshenko said this, speaking to the students of Ivano-Frankivsk National Technical University of Oil and Gas on Wednesday.
"We have to restore the Ukrainian oil and gas industry... We have discussed [with the scientists - ed.] how important it is to return them now, to bring legal action [against Russia - ed.] and get our offshore fields back, including Odeske and Bezimiane," he said.
As reported, Russian Prime Minister Dmitry Medvedev signed a decree that could ban operators from using the fields in the Azov and Black Seas, which were given the right by Ukraine before the occupation of Crimea.
