Chairman of the Board of Directors of Group DF Dmytro Firtash says a dialogue with Russia is necessary.Dmytro Firtash said this in an interview with the outlet ukraina.ru."We must stop playing games, we need to talk with Russians directly. It is obvious that the Minsk agreements, Normandy Four will not resolve economic problems. We may like it or not, but we have to sit and talk. We have to find solutions to all problems. Even the problem of Crimea can be resolved," he said.He emphasizes that Ukraine needs all markets - the markets of Europe, and Russia, and China."We say honestly: 'we struggle for markets from Lisbon to Vladivostok.' We want the European investment, as well as Russian investment and China's investment. We want markets, partners. The Russian market is particularly important to Ukraine. Whatever is said we must use it. Of course, the current authorities are not ready to discuss this. But I am sure that by 2019 you will see different feelings and a different political landscape," he said.He noted that the breach of relations with Russia has made performance of many Ukrainian enterprises unprofitable.As Ukrainian News Agency earlier reported, in the fall of 2014 Dmytro Firtash viewed as promising the creation of a common market with participation of countries of the European Union, the Customs Union of the Single Economic Space (Russia, Belarus, Kazakhstan) and Ukraine.
