Davos 2011: What's on the diary?

Russia's president will tell some of the world's most important business executives that his country is a place where they should invest.

Dimitry Medvedev is arriving later than planned at the annual gathering of the World Economic Forum in the Swiss ski resort of Davos because of the Moscow airport bombing.

Some 2,500 business and political leaders are there to discuss the outlook for the world economy.
