According to him, it would not be true to say that Ukraine will join the EU in six months, a year or two years.

“We need to be honest ... It will probably take 15 or 20 years, this is a very long process,” RIA Novosti quoted him as saying on Radio J radio station.

Earlier, Russian Deputy Foreign Minister Oleksandr Grushko said that Ukraine's membership in the European Union would mean the end of the association.
