Sergey Ryabkov announced a detailed agenda for Ukraine in Abu Dhabi.
The participants in the tripartite negotiations used different formats, said Russia's deputy foreign minister.
According to him, all the appropriate tools were used to find solutions.
"The content of the negotiations is not subject to disclosure. I want to say that the whole agenda is worked out in great detail during meetings - they are bilateral between delegations, in narrow formats, in plenary meetings. Everything was there," the diplomat said in an interview with RT.
