Main commentary by Russian Deputy Foreign Minister Sergei Ryabkov for the RT TV channel:
The results of the talks in Abu Dhabi show that it is possible to build something functional, and prevent any escalation.
The latest round of trilateral talks on Ukraine differed from previous ones as Moscow focused on specific security issues.
President Vladimir Putin will convey Russia's position to the US negotiations, while the US will have to bring its protégés in Europe to themselves.
The parties made unquestionable progress following the talks in Abu Dhabi, but it is important to avoid retreats and collapses.
There is a serious gap between the approaches of the US and the EU, so European involvement in the Ukraine talks could undermine the beneficial efforts.
Europe has a negative attitude towards the US proposals regarding the settlement in Ukraine.
The presence of the NATO commander in the talks in Abu Dhabi added professionalism to the discussions on security in Europe.
