Another round of talks between Moscow and Washington on a new strategic arms deal will open in Geneva on Monday, a Russian Foreign Ministry spokesman said on Friday.

"A considerable amount of work has been done towards preparing the new arms cut pact, both at political and expert levels. It didn't stop even during the New Year holidays. The next round of talks between the two sides will take place in Geneva on February 1," said Andrei Nesterenko.

The new treaty's outline, as agreed by the Russian and U.S. presidents, includes cutting nuclear arsenals to 1,500-1,675 operational warheads and delivery vehicles to 500-1,000.

Disagreements over verification and control procedures have prevented Moscow and Washington from signing a new deal before the New Year break to replace the Strategic Arms Reduction Treaty (START 1), which expired on December 5.
