美国总统奥巴马说，他将很快安排一个议程，寻求一个没有核武器的世界。
奥巴马在法国东部城市斯特拉斯堡对学生说，核武器的扩散能毁灭地球上的任何一个城市。他说，他将于星期天在布拉格概述他的建议。
早些时候，萨科奇称赞奥巴马总统和俄罗斯总统梅德韦杰夫星期三宣布恢复延长限制远程核武器条约会谈的计划。
奥巴马强调同俄罗斯对话的重要性。但是他再次批评莫斯科去年入侵格鲁吉亚。他还强调保留所有欧洲国家自治的重要性。
在星期五举行的两天北约首脑会议之前，奥巴马抵达斯特拉斯堡。
U.S. President Barack Obama says he soon will lay out an agenda to seek a world without nuclear weapons.
Speaking to students in the eastern French city of Strasbourg, Mr. Obama said the spread of nuclear weapons could lead to the extermination of any city on the planet. He said he will outline his proposals in Prague Sunday.
Earlier French President Nicolas Sarkozy praised Wednesday’s announcement by President Obama and his Russian counterpart Dmitri Medvedev on plans to resume talks on extending a treaty limiting long-range nuclear arms.
Mr. Obama stressed the importance of dialogue with Russia. But he repeated his criticism of Moscow’s military sweep into Georgia last year. He also stressed the importance of preserving the autonomy of all European countries.
Mr. Obama traveled to Strasbourg ahead of Friday’s opening of a two-day NATO summit.
