“It is necessary both primarily from the point of view of bilateral Russian-US relations and from the point of view of having a serious conversation at the highest level about international affairs and on regional problems, including, of course, about the crisis over Ukraine" Peskov said.

Meanwhile, Russian and Ukrainian negotiators were in Istanbul on Friday for what was billed as their first direct peace talks in more than three years.

Commenting on the Istanbul talks, Peskov said that the Russian negotiating team was in constant communication with Moscow and that President Putin was receiving real-time updates.
