Guangzhou will host the International Tourism Industry Expo 2015 at the Pazhou International Exhibition and Convention Center from Sept 10 to 13.

The annual event in Guangdong's capital, launched in 2005, has become China's largest tourism fair, attracting a growing number of visitors from home and abroad, said Li Jianyi, director of the marketing development department with the Guangdong provincial bureau of tourism on Wednesday.

More than 36,500 buyers and around 500,000 visitors from more than 50 nations and regions are expected.

The expo will include seminars, lectures, tourism presentations and cuisine fairs.

Last year's event saw more than 122.7 billion yuan ($19.17 billion) worth of co-operative and trade contracts signed.
