Amazon.com, a US-based e-commerce operator, will establish its eighth logistics base in China, authorities in Beijing  said on Monday.

The 100,000-square-meter base will be set up at the Kunshan Huaqiao Economic Development Zone in Kunshan city in eastern Jiangsu Province. The two warehouses will be put into use in July and September respectively, Xinhua news agency reported.

"All the online orders in the Yangtze River Delta region will be dealt with and delivered from the newly built logistics centre in Kunshan upon its completion in July," said a source close to the centre. The source said delivery time will be shortened to half a day as a result.

Upon completion, the logistics base will be the largest among those already in operation in China.

Amazon has so far established seven logistics bases in several Chinese cities, including Beijing, Shanghai, Guangzhou and Suzhou, to offer millions of goods to consumers, including electronic products, daily necessities and automobile goods.

Kunshan Huaqiao Economic Zone was chosen from many other Chinese sites for its economically important location in the Yangtze River Delta region and its vigorous efforts in developing the local service industry, the report said.

Amazon rents web services and storage to companies.
