It is the first time that so many overseas representatives will participate in an international forum on Tibet, an official statement said today.
The topic of this year's forum, to be held between August 12-13, is "Opportunities and choices for Tibet's development."
Issues concerning the protection of Tibetan culture and environment will also be highlighted, state-run Xinhua news agency reported.
After the forum, nearly 100 representatives from China and abroad will conduct field trips in Lhasa and Nyingchi, to "experience the real Tibet," the statement said.
The forum was first held in 2007 in Vienna, Austria.
