Russian Foreign Minister Sergei Lavrov says talks with the U.S. on a new nuclear arms treaty will resume in early February.
Lavrov said Friday that Russian and U.S. military officials are holding talks in Moscow to clarify differences over verification and missile defense.
President Barack Obama and his Russian counterpart Dmitry Medvedev agreed last July to seek a new deal to replace the 1991 accord that expired last month. It proposes slashing the arsenals of both sides to between 1,500 and 1,675 warheads each.
U.S. officials said Wednesday they expected talks to resume Monday in Geneva.
Moscow and Washington both want to reach a new accord quickly to give credibility to their efforts to persuade Iran and North Korea to abandon their nuclear programs.
