Moscow ? Russia’s foreign minister said Saturday he believed international talks with Iran over its atomic program were still possible, maintaining that Russia could help bridge differences with other negotiating partners, including the United States.

President Vladimir Putin met Saturday with Iran’s top nuclear negotiator, Ali Larijani, ending two days of talks that signaled a renewed Moscow effort to force Iran to freeze its uranium enrichment effort. Iran, however, has so far snubbed Moscow’s proposal to host its enrichment program.

The six nations agreed to hand the Iranian dossier to the U.N. Security Council after Tehran rejected their demand to suspend enrichment, but Russia and China opposed European-drafted sanctions and called for more talks.
