About 91 billion yuan in deals were signed at a recent international high-tech trade fair in the southwestern metropolis.

The event attracted 180 delegations from 35 countries and regions including first-time exhibitors from Denmark, Luxembourg and Hungary.

Agreements on patented technologies signed during the four-day fair included licensing deals on frontier tech and contracts with experts on smart grids, clean coal, eco-friendly materials and industrial robots, organizers said.

China's high-tech sector generated more than 8 trillion yuan and had $550 billion in exports last year.
