Russia and the United States have a good chance at signing a new nuclear arms reduction deal before year's end, but other nuclear powers must join disarmament efforts to move toward a nuclear-free world, Russian President Dmitry Medvedev said in remarks released Saturday.

Medvedev told the German magazine Der Spiegel that the US-Russian arms control talks have been going at a good pace. "We have every chance to agree on a new treaty, determine new (weapons) levels and control measures and sign a legally obliging document in the end of the year," he said in remarks released by the Kremlin.

Moscow and Washington are negotiating a successor deal to the 1991 Strategic Arms Reduction Treaty that expires on December 5. Efforts to slash US and Russian nuclear arsenals have been a major part of US President Barack Obama's push to "reset" relations with Russia, which became tense under the previous administration.

Russian and US diplomats are set to launch another round of negotiations in Geneva on Monday. A Russian Foreign Ministry spokesman has voiced hope it would be conclusive.
