US pair Davis Polk & Wardwell and Simpson Thacher & Bartlett have scored mandates on the planned New York listing of Chinese internet company Baidu’s online travel unit. 

The listing of Qunar Cayman Islands, valued at $125m (£78m), comes as China’s big four internet companies compete with each other to grow their businesses abroad. The initial public offering (IPO) is thought to be the largest by a Chinese company in the US for two years.
