About 470 domestic and overseas information technology companies promised to participate in what has been described as the world's fourth largest computer product exhibition, scheduled for October 13 to 17 in Dongguan.

Officials with the municipal government of Dongguan, in south China's Guangdong Province, said Thursday that 1,200 booths at Dongguan International Convention and Exhibition Center have been booked by participants.

The companies include 287 local enterprises and 183 firms from about 20 countries and regions, such as the United States, Japan, Germany, the Republic of Korea and Taiwan, Hong Kong and Macao.

Among products to be exhibited will be computers, computer parts, telecommunications and network products, consumer electronic products, and electronic-commerce products.
In the past decade, billions of U.S.-dollar investment by overseas IT companies, including Taiwan, Hong Kong, the United States and Japan, has turned Dongguan one of the leading manufacturing centers of IT products.

Organizers of the exhibition said exhibition is expected to attract more than 300,000 visitors, making it the fourth largest of its kind, following the Compex in the United States, Cebit in Germany, and Computex in Taiwan.
