Every year in late January, global leaders in business, politics, academia and other fields get together in Switzerland to discuss the various challenges faced by the world.

This annual meeting of the World Economic Forum, dubbed Davos after the Swiss resort at which it is held, is in its 43rd year and continues to grab the media spotlight for the insights it gives into the global economy.

Over 2,500 participants from more than 100 countries will attend Davos, which is being held from Jan. 23 to 27. Russian Prime Minister Dmitri Medvedev, British Prime Minister David Cameron, German Chancellor Angela Merkel, Italian Prime Minister Mario Monti and other leaders from some 50 countries will address the invitee-only audience.
