PARIS, Dec 3 (Reuters) - The West should consider how to address Russia's need for security guarantees if President Vladimir Putin agrees to negotiations about ending the war in Ukraine, French President Emmanuel Macron said in remarks broadcast on Saturday.Russia and the United States have both said this week they are open to talks in principle, though U.S. President Joe Biden said he would only talk to Putin if the Kremlin chief showed he was interested in ending the war.Many in Ukraine and the West are strongly opposed to any negotiation with Putin that would reward him with concessions after nearly 10 months of war, especially as Ukraine has driven back Russian forces from large areas in the past three months.But Macron's remarks suggested he was sympathetic to Moscow's need for security guarantees - a demand that was the focus of intense but failed diplomacy in the run-up to the war.On Feb. 8, just weeks before Russia's invasion, Putin said at a joint news conference with Macron in Moscow that Russia would keep trying to obtain answers from the West to its main three security demands: no more NATO enlargement; no missile deployments near its borders; and a scaling back of NATO's military infrastructure in Europe to 1997 levels."
