Moscow has ambitions to hold this summer a conference on the Middle East analogous to that in Annapolis conference in the US state of Maryland last November. Russia, a member of Middle East Quartet along with the European Union, the United Nations and the United States, has long emphasized its role as a chief negotiator in Palestinian-Israeli peace talks.
