On July 19, the Bloomberg news agency reported, citing two people who were in attendance at a closed-door speech of Putin, that the leader, during his recent meeting with Trump in Helsinki, said he had proposed holding a referendum in eastern Ukraine under the auspices of international organizations so that local residents could determine the status of the breakaway territories themselves.
"This proposal was discussed, however no reaction has followed yet," Ushakov told Izvestia newspaper in an interview published on Wednesday.
Ushakov added that Russian Foreign Minister Sergey Lavrov and US State Secretary Mike Pompeo within the framework of the Helsinki summit discussed the issue of Russian diplomatic property in the United States.
