Alibaba Group, China, invested an additional $3.3 billion in Cainiao Smart Logistics Network, growing its majority stake in the China-based shipping affiliate.

This move supports Alibaba’s new retail strategy to provide a seamless blend of online and offline shopping for consumers.

“Cainiao strives to enhance service and user experience for merchants and consumers through superior technology and digital solutions, both within China and around the world. We are committed to supporting its ongoing development, to realizing greater synergies throughout the entire Alibaba economy and accelerating digitization of the logistics industry,” says Daniel Zhang, executive chairman and CEO of Alibaba.

Cainiao operates as a digital platform to connect a network of express delivery companies in China.

Alibaba’s investment will continue to build out the network and technology, which includes smart warehouses, robot fulfillment and algorithms to boost efficiencies in shipping.
