Skadden, Arps, Slate, Meagher & Flom and Ropes & Gray have the lead roles on a $1.38 billion deal that will see an investor consortium led by Alibaba Group Holding Ltd. take a 10 percent stake in Chinese courier ZTO Express (Cayman) Inc.

As part of the deal, Alibaba’s logistics arm, Cainiao Network, will cooperate closely with Shanghai-based ZTO on delivery, warehouse management and technology. Alibaba co-launched Cainiao, a logistics data company, in 2013, alongside Fosun Group, department store operator Intime Group, and a group of Chinese couriers—including ZTO. The Hangzhou-based e-commerce giant became a majority shareholder of Cainiao last year following an $807 million investment.
