KUNMING - Southwest China's Yunnan province reported a more than tenfold increase in cross-border e-commerce trade volume in the first 11 months of this year, local customs authorities said Tuesday.

The import and export value of cross-border e-commerce in the province reached 640 million yuan ($97.7 million), 13.3 times higher than the number for the same period last year, according to the Kunming customs.

The development of cross-border e-commerce in Yunnan has picked up pace since the provincial capital Kunming was designated a national-level comprehensive test zone for cross-border e-commerce.

To meet the demand of the booming sector, customs authorities of the region have been working to streamline customs clearance further and improve logistic efficiency.
