Moscow and Washington should re-establish direct contacts between their military and foreign policy chiefs, Russia’s new ambassador to Washington, Anatoly Antonov, said Wednesday.

“The time has come to resume joint meetings of Russia’s and the United States’ foreign and defense ministers in a ‘two plus two’ format,” Antonov said in an interview published on the Kommersant business daily’s website.

Military contacts between Moscow and Washington were frozen in 2014 due to the Ukraine crisis.

Antonov also called for meetings between the heads of Russia’s Federal Security Service and Foreign Intelligence Service and the U.S. Federal Bureau of Investigation and Central Intelligence Agency.

A “working cooperation” between Russia’s Security Council and the U.S. National Security Council could also help fight terrorism and cyberthreats and help strategic stability, he said.

Antonov, a former deputy foreign minister, is subject to European sanctions over his role in the conflict in Ukraine.
