A new treaty limiting U.S. and Russian strategic nuclear arsenals could be signed within two or three weeks, Russian news agencies cited Foreign Minister Sergey Lavrov as saying today. Lavrov spoke as U.S. and Russian negotiators resumed talks in Geneva on a successor to the 1991 Strategic Arms Reduction Treaty, which expired in December, AP reported. "We would push for a conclusion in two to three weeks," Lavrov was quoted as saying. "For this there is every chance."
