Rubio called the negotiations between the US, Russia and Ukraine in Abu Dhabi productive.
"It seems that the negotiations in Abu Dhabi were very productive. Clearly, much work remains in this direction.
This does not mean that a solution will be found in the next 24 hours or something like that. But it is very important that the Europeans participate in the negotiations.
Our goal in the end is to expand the tripartite format so that not only the USA, Ukraine and Russia, but also European countries will be represented at the negotiating table."
- said the US Secretary of State.
