The Foreign Ministry said Thursday that Russia was proposing a new version of the Treaty on Conventional Armed Forces in Europe, which it suspended more than a year ago, and could once again honor the agreement if the United States and its NATO allies accept the changes.

"Russia believes that chances to revive the treaty still exist," Foreign Ministry spokesman Andrei Nesterenko told reporters.

He said Russia was proposing to negotiate revisions in the treaty with the United States. The country had formally submitted its proposals for changes in the treaty to other partners in the CFE treaty earlier this month.

The 1990 treaty limits the number of tanks, aircraft and other heavy non-nuclear weapons that could be deployed west of the Ural Mountains. A revised version was signed in 1999, but NATO has not ratified it, and in 2007 Russia suspended its participation.
