Russia's new ambassador said Moscow and the United States should resume top-level diplomatic talks between defense and foreign policy chiefs, according to a report.

Renewed cooperation between the two countries could help help fight terrorism and cyber threats as well as foster stability, Anatoly Antonov told a Russian-language newspaper on Wednesday, according to Reuters.

"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," he said.

Antonov, who is seen as a hardliner, also suggested Russia's security and foreign intelligence services meet with the FBI and CIA.

The U.S. holds so-called two-plus-two meetings with other countries and allies such as Japan that include the defense secretary, secretary of state, and their foreign counterparts.

Diplomatic relations with Russia have soured in recent years, especially since its invasion and annexation of Crimea in 2014, and Moscow has since stoked international concern — and ire among members of Congress — for fueling a conflict in Ukraine and meddling in the U.S. presidential election last year.

Antonov, previously Moscow's deputy foreign minister, was sanctioned by the European Union due to the Ukraine conflict.
