World leaders concluded on Sunday the five-day annual meeting of the 41st World Economic Forum (WEF) in Swiss Alpine ski resort Davos.

Davos held the last four discussions or debates on Sunday on policy priorities, global risks and emerging issues for 2011 as well as the spirit of Davos as a conclusion for this year's WEF Annual Meeting.

During the past five days, over 2,500 world leaders from industry, government, academia, civil society and the media had discussions on a wide range of topics mainly including world economic recovery, global risks, Doha Round of global trade talks and climate change, etc.

This year saw cautious optimism come back to the Davos Annual Meeting after two years of worries and fears on global economic crisis.

World leaders generally take emerging markets like China, India and Brazil as significant driving forces for the world economic recovery, and the developed countries as stragglers with problems of sovereign debt and budget deficits hanging over in the coming years.

China attracted even more attention during this year's meeting than the previous years as it becomes a leading emerging market, with particular attention on its participation in the global trade as this year marks the 10th anniversary of China's accession into the the World Trade Organization (WTO).

According to officials with the WEF, the Davos Annual Meeting provides a rethinking of our systems and exploration of strategies and solutions that have positive transformational implications.
