Russia, U.S. fail to agree on missile shield

By Kristin Roberts and Christian Lowe

MOSCOW (Reuters) - Russia and the United States failed on Tuesday to find common ground over U.S. plans to deploy parts of a missile defence shield in eastern Europe.

Russian Foreign Minister Sergei Lavrov said he had agreed with U.S. Secretary of State Condoleezza Rice after six hours of talks in Moscow to study further U.S. proposals aimed at allaying Russian concerns about the shield.

The U.S. plan has plunged relations between the two countries to a post-Cold War low and negotiations on the proposals have already been running for almost six months.

"On the matter of principle the positions of our two sides have not changed," Russian Defense Minister Anatoly Serdyukov said after taking part in the talks with Rice, Lavrov and U.S. Defense Secretary Robert Gates.

Time is running out to reach a deal before U.S. President George W. Bush's administration leaves office in under a year.

The United States says it wants to install radar and missile installations in Poland and the Czech Republic to protect against missile strikes from so-called "rogue" states, specifically Iran.

Russia says a shield would upset the strategic balance and threaten Russia's own security. It has said it may return to its Cold War posture of targeting its nuclear missiles at Europe if the shield is built.

Briefing reporters after their meeting, Rice and Lavrov appeared upbeat and friendly, passing notes and joking together when a Russian reporter addressed her as "Mrs Gates." The last such four-way meeting was in Moscow in October.
