KIEV, August 27, /ITAR-TASS/. Ukrainian President Pyotr Poroshenko has discussed the implementation of Ukraine’s association agreement with Russian President Vladimir Putin at a highly professional level, Ukraine’s Foreign Minister Pavel Klimkin said in a live interview with Ukraine’s ICTV channel late on Tuesday.

“The discussion was complicated but interesting,” the Ukrainian minister said, adding that de-escalation in Donbas was the underlying principle for Ukraine.

“The most important thing is to have a clear understanding what is necessary for implementing the Ukrainian president’s peace plan,” Klimkin went on to say.

“I hope that we can and should find a solution. It is peace and de-escalation. But it should not be a solution at a price of a compromise. A democratic European and unified Ukraine is the invariable pre-condition for any solution. All other issues can be discussed,” the Ukrainian foreign minister stressed.
