Europe's involvement in the negotiations on Ukraine could mean the cancellation and disruption of the efforts that have so far carried a "positive charge" - Ryabkov.
European countries are negatively inclined towards US proposals for a settlement and are unable to accept Russian approaches, says Deputy Foreign Minister of Russia Sergey Ryabkov.
In response to the question of whether territorial issues were discussed in Abu Dhabi, Ryabkov said that the entire agenda is being worked out "in great detail" in various formats.
Sergey Ryabkov is part of the Russian negotiating delegation.
