"Our proposal remains on the table. The new U.S. administration will encounter serious problems with regard to the implementation of its third missile site plan in Europe. We are not exerting any pressure on the U.S. administration here," Andrei Denisov said.
He added that Russia's proposal was more "cost effective" than other projects since the radar station was already out there and could operate "for decades to come."
Moscow has strongly opposed the possible deployment by the U.S. of 10 interceptor missiles in Poland and a radar in the Czech Republic as a threat to its security and nuclear deterrence. Washington says the defenses are needed to deter possible strikes from "rogue states."
Russia has offered the United States the use of its radar stations in Armavir in southern Russia and Gabala in Azerbaijan as alternatives, but Washington said they would only be used as "supplements," if at all.
Russian President Dmitry Medvedev has vowed to retaliate over the U.S. missile shield plans in Central Europe.
