Manmohan leaves for Moscow today on a three-day visit, during which he will hold talks with Russian President Vladimir Putin.

One of the key defence-related agreements India and Russia are set to sign in Moscow during Singh's visit is on Intellectual Property Rights (IPR) which is expected to pay the way for joint designing and manufacture of futuristic weapon systems including supersonic anti-ship missiles for the Indian Navy, official sources said here yesterday.

The two countries will also sign an agreement on technology safeguard relating to Russia-designed space communication system to implement last year's accord on cooperation in space navigation system.

Another agreement will be on amending the existing bilateral ten-year defence accord, which expires in 2010, under which India will acquire military equipment worth 20 billion dollars from Russia.
