American electronic commerce and cloud computing company Amazon.com Inc, in a bid to control escalating expenditure, is aggressively expanding its logistics operations in China.
Some analysts say the move could help position Amazon to offer shipping services to other companies, Reuters reported.
Meanwhile, a spokeswoman for Amazon declined to comment on the development.
"These are major gateway ports. They appear to be laying the foundation for a large forwarding operation," said John Manners-Bell, who heads Transport Intelligence, a logistics analysis firm.
"They're moving into something that could be potentially very treacherous," said Andreas Krueger, head of ocean freight for DHL Global Forwarding in US.
Headquartered in Seattle, Washington, Amazon is the largest Internet-based retailer in the United States. The company produces consumer electronics-notably, Amazon Kindle e-book readers, Fire tablets, Fire TV and Fire Phone-and is the world's largest provider of cloud infrastructure services (IaaS).
Amazon also sells certain low-end products like USB cables under its in-house brand AmazonBasics.
