Russia is studying a set of written proposals it has received from Washington on missile defence, a Russian foreign ministry spokesman was quoted by Russian news agencies as saying on Thursday.
The proposals are a follow-up to a visit to Moscow last month by US Defence Secretary Robert Gates and Secretary of State Condoleezza Rice, said the spokesman, Mikhail Kamynin, quoted by Interfax.
"The American side late yesterday evening finally handed to Russia written proposals on missile defence. We are studying them," he said.
Washington's plans to place missile defence facilities in the Czech Republic and Poland, countries once ruled from Moscow, have prompted a severe deterioration in US-Russian ties.
Russia has proposed that the United States instead use a Russian-controlled radar in ex-Soviet Azerbaijan.
The US side at last month's talks made new proposals for creating a Europe-wide missile defence scheme that would include Russia.
Washington insists that its plans to place a radar in the Czech Republic and interceptors in Poland are not aimed against Russia but at "rogue states" such as Iran.
