TEHRAN – Former president Mohammad Khatami heads to Davos, Switzerland, on Tuesday to attend the Annual Meeting of the World Economic Forum from January 24-28.

The theme of this year's meeting is "The Shifting Power Equation" that reflects the elements that will shape the global priorities in 2007.

Khatami, a frequent guest, will take part in one Middle East session titled "Enough is Enough." Another on the future of the region includes European Union foreign policy chief Javier Solana.

The lineup for this year's meeting lacks a big-hitter from The White House, but several Bush administration officials and presidential hopefuls will attend. The guest list includes Palestinian leader Mahmoud Abbas, Jordan's King Abdullah II, Lebanese Prime Minister Fouad Siniora and key Shia, Sunni and Kurdish politicians from Iraq.

German Chancellor Angela Merkel will open the five-day meeting in her new role as head of the 27-nation European Union and the Group of Eight industrialized countries, and British Prime Minister Tony Blair will close it, but much of the talk in between will focus on the shift in power away from Europe and the United States to emerging countries in Asia and Latin America.

Previous key U.S. speakers at the forum have included former U.S. President Bill Clinton and First Lady Hillary Clinton, Vice Presidents Al Gore and Dick Cheney and Secretaries of State Madeleine Albright and Colin Powell. Condoleezza Rice, the current secretary, addressed the meeting by satellite link last year.
