Asked whether the Normandy summit would take place, he said: "I think no, definitely no ... Russia has repeatedly announced – both [Vladimir] Putin and representatives of the Kremlin said – that it is necessary to meet when there are some results and there is something to discuss. While we see Russia putting forth its demands that Ukraine categorically rejects, so there is no sense in meeting."
Sazonov suggested that Russia "will block the meeting, refuse it."
"We could use the meeting – we will once again highlight the problem, again draw the attention of Germany and France to it. Perhaps we will seek tougher sanctions, show Russia's inability to negotiate. But the Kremlin also understands this very well, therefore the meeting is most unlikely; so is an exchange of prisoners. Russia needs no people – they are ready to return our captives only in exchange for political concessions," the expert said.
