MOSCOW — U.S. Secretary of State Hillary Rodham Clinton said today t American and Russian negotiators are "on the brink" of agreement on a nuclear arms reduction treaty.

After meeting with Russian President Dmitry Medvedev, Clinton said she expects a treaty-signing soon, although she mentioned no date or place.

"Our negotiating teams have reported that they have resolved all of the major issues and there are some technical issues that remain," she said at a joint news conference with Russian Foreign Minister Sergey Lavrov.

"But we are on the brink of seeing a new agreement between the United States and Russia," Clinton added.

Her remarks were more pointedly optimistic than just a day earlier, when she cautioned against presuming success soon.
