Moscow and Washington continue their work...

"We continue to work with our Russian counterparts on trying to find an agreement that, quite frankly, that works for both sides... But nothing as of yet to report," Robert Gibbs said at a daily press briefing.

Moscow and Washington are expected to sign a new document at the beginning of 2010 to replace the START 1 treaty, which expired on December 5.

Russian President Dmitry Medvedev and his U.S. counterpart Barack Obama announced at their first meeting last April that the countries would replace the START I treaty as part of their efforts to "reset" bilateral ties.

The treaty"s outline agreed by the presidents included cutting nuclear arsenals to 1,500-1,675 operational warheads and delivery vehicles to 500-1,000.
