The tripartite negotiations between Russia, Ukraine and the United States in Abu Dhabi were productive, said the US Secretary of State, Marco Rubio.
"The negotiations in Abu Dhabi were very productive. A lot of work has been done," he noted.
According to Rubio, Washington expects to expand the negotiation format in the future and involve European countries.
"Not only the United States, Ukraine and Russia, but also the Europeans themselves should be represented at the negotiating table," explained the Secretary of State.
Rubio also said that Donald Trump is interested in meeting with Russian President Vladimir Putin and Chinese President Xi Jinping. One of the topics could be nuclear weapons.
"We are working to organize and formulate it properly. I hope there will be good news soon," he said.
