Russia’s Foreign Minister Sergei Lavrov on Friday called the most recent back and forth between Washington and Pyongyang “unacceptable”, saying that the countries involved should cool their hotheaded behavior.

Speaking at a press conference in New York a day after his address to the UN General Assembly, Russia’s top diplomat once again reiterated the “suspension for suspension” proposal, a joint- initiative with Beijing that would halt joint U.S. – ROK military exercises in exchange for a moratorium on DPRK weapon testing.

“The exchange of threats is quite bad, unacceptable … We have to calm down the hot heads,” Lavrov said in comments
