Jan 29 (Reuters) - Chinese robovan developer Zelostech said on Thursday that e-commerce giant Alibaba's ​logistics arm, Cainiao, will take a ‌stake in the company. The deal will create a business valued ‌around $2 billion, the Wall Street Journal, which first reported the news, said. A spokesperson for the robovan developer said "Cainiao will not become a controlling ⁠shareholder of Zelostech." "Zelostech and Cainiao’s autonomous-driving unit have entered into a ​deep strategic integration, jointly building a RoboVan ‌Super Carrier in the unmanned freight sector," an emailed statement from Zelostech said. The Journal reported that Cainiao's ​autonomous-driving unit will be ​folded into Zelostech, adding that Zelostech will operate both brands simultaneously.
