Skadden Arps Slate Meagher & Flom and David Polk & Wardell have won a roles advising Chinese internet platforms Dianping Holdings and Meituan on their mega-merger.

Legal Week understands that Davis Polk & Wardwell is representing Meituan, while Skadden is acting for Dianping.

Financial details of the deal were not disclosed but the merger announced today is set to create a platform valued at between $15bn (£9.7bn) and $20bn (£13bn), according to reports.

Meituan is part-owned by Alibaba Group Holding while Dianping is backed by Alibaba's rival Tencent Holdings.

The two groups, which are similar to western site Groupon, are expected to dominate China's market for online to offline (O2O) services selling food and entertainment packages.

Skadden is employing a team based across its Hong Kong and Shanghai offices including corporate partners Julie Gao, Haiping Li and Will Cai.

Gao and Cai also headed up Skadden's team when it acted opposite Simpson Thacher & Bartlett to advise on a merger between two of China's largest taxi apps, Didi Dache and Kuaidi Dache, earlier this year.

Skadden acted as international counsel for Didi on the deal, while Fangda Partners provided People's Republic of China counsel.

The growth in China's mobile transport app market has been driven by a surge in the number of people using their smartphones to access the internet.
