Simpson Thacher & Barlett, Fangda & Partners, Kirkland  & Ellis and Zhong Lun Law Firm have scored roles on the first-round fundraising of Zhejiang Cainiao Supply Chain Management Co, a logistics firm backed by Alibaba.

Cainiao has raised 10 billion yuan ($1.54 billion) in its first round of funding, according an estimate by the Chinese media group Caixin, giving it a valuation of 50 billion yuan. It was founding by Alibaba three years ago.

The funding round attracted a number of high-profile, mostly international funds including Singapore’s Temasek Holdings and GIC, Malaysia's Khazanah Nasional, and China's Primavera Capital, Alibaba said in a statement.

Simpson Thacher & Barlett, Fangda & Partners represented Cainiao in the deal. Fangda’s team was led by corporate partners Jonathan Zhou and Silvia Gong. Global Law Office represented China's Primavera Capital, led by partners Liu Jinrong and Sun Shifang. 

Kirkland and Zhong Lun represented  Khazanah Nasional Bhd. Zhong Lun’s team was led by Shanghai-based partners Zhao Jing and Zhang Xinlu.

Alibaba is seeking to take a lead role in developing China's fragmented package delivery industry, as e-commerce spreads beyond urban hubs and requires a more robust logistics network. In partnership with delivery businesses, Cainiao crunches reams of data on everything from order trends to delivery routes and weather patterns to increase efficiency.Alibaba said it would work with investors to further build out its ”big data logistics network.”
