Russia will offer NATO in September a detailed proposal to build a joint collective security system that would cover the Northern Hemisphere, Dmitry Rogozin, Russia's envoy to the alliance, said Tuesday.

President Dmitry Medvedev told a summit with European Union leaders last week that he believed that NATO was unable to provide security for the continent of Europe.

Moscow views NATO's expansion eastward as a threat, and Medvedev has called for a summit to discuss a post-Cold War security umbrella that could supersede NATO. Medvedev says none of the current international bodies adequately represented all of Europe.

"During the September meeting of the Russia-NATO Council … we plan to offer a more detailed picture linked to the Russian president's proposal," Rogozin told a teleconference from Brussels.

"Russia is not sitting on the fence, we are not dragging our feet, waiting for a miracle," Rogozin said. "We propose our own formula of security."

He gave no details of the proposals but said Medvedev's remarks at the summit were now "discussed with avid interest in European capitals."

"The talk is really about security … for the entire European continent … for the entire Northern Hemisphere of the world, in a broader sense, from Vladivostok to Vancouver," Rogozin said.
