Computex Taipei, Asia's largest computer show, concluded on Saturday, attracting more than 38,600 buyers from 166 countries and regions, with mainland buyers being the strongest presence.

Following the Chinese mainland, the strongest presence were from the United States, Japan, China's Hong Kong and the Republic of Korea, said Walter Yeh, executive vice president of the island's external trade development association.

Yeh said that, this year, mainland buyers showed strong annual growth from 3,600 to more than 5,000. In 2012 and 2013, the mainland buyers were listed as the third largest source of buyers.

Featuring more than 1,700 exhibitors with more than 5,000 booths, the computer expo is predicted to have generated over 25 billion U.S. dollars in business, Yeh said.

This year, the Computext highlighted wearable device, touch applications and the Internet of Things, with 120 forums held alongside, said Yeh, praising the annual expo as a great platform for showcasing both hardware and software.
