Russian president Dmitri Medvedev says his country is ready for a reduction of strategic weapons in an arms-control agreement with the US.

Medvedev is due to meet US president Barack Obama next month to discuss replacing the Strategic Arms Reduction Treaty. Medvedev says Moscow wants binding arrangements outlined in a single document.

He says Russia wants "a verifiable and real" reduction of offensive weapons as part of that deal.

Russian officials have said that US plans for a missile defence system will be problematic in the talks, though the US says the shield is designed for threats from Iran, not Russia.

Medvedev was speaking to reporters after meeting Dutch prime minister Jan Peter Balkenende.
