Moscow: Russia wants to resume regular consultations with the US on a range of security issues, including missile defence, a top Russian military official said.
The talks could serve to bridge the yawning divisions between two nations on a series of defence matters - most notably Washington's ongoing plans to install missile shields that Moscow says undermine its own military strategy.
Russian Defence Minister Sergei Shoigu said in a telephone conversation with his US counterpart Chuck Hagel that "no setbacks, and least of all chaos, should hamper dialogue between the military of the two great powers".
"We are concerned about the further development of the situation around the European missile shield, and our defense minister proposed to resume regular consultations on this issue," Deputy Defence Minister Anatoly Antonov said, describing the telephone conversation.
Shoigu confirmed his written invitation to Hagel to attend an international conference on European security in Moscow in May.
He also suggested that a Russia-NATO Council meeting could be held on the sidelines of this conference, tentatively set for May 23-24.
"Russia could unveil its plan for the West-2013 strategic exercise in which NATO has shown great interest and to discuss military cooperation with NATO," Antonov said.
Russia and NATO initially agreed to cooperate on the so-called European missile defence system at the Lisbon summit in November 2010.
Further talks between Moscow and the alliance have foundered over NATO's refusal to grant Russia legal guarantees that the system would not be aimed against Russia's strategic nuclear deterrent.
NATO and the US insist the shield is designed to defend NATO members against missiles from emerging threat nations like North Korea and Iran, and would not be directed at Russia.
The alliance has vowed to continue developing and deploying its missile defences, regardless of the status of missile defence cooperation with Russia.
