Transactions in science and technology deals reached nearly 500 million yuan ($75.6 million) during the China (Dongguan) International Science and Technology Cooperation Week, according to the organizers.

More than 100 intentional agreements in science and technology were signed during the three-day event, which concluded Sunday in Dongguan, a traditional manufacturing and trade hub in the Pearl River Delta.

A number of new innovative science and technology projects from more than 300 domestic and overseas research and development institutes were displayed during the event, which was inaugurated in 2004.

"Innovation in technology will help the city better improve its industrial structure," said Bai Tao, vice-mayor of Dongguan.

At a forum focused on science and technology innovation, Robert. F. Curl, who was awarded the Nobel Prize in Chemistry in 1996, shared his views on China's need to develop artificial intelligence, new energy and biology.

"As a rising economy, China will play a major role in research and development of new technologies, which will, in turn, help upgrade its economy," he said.
