The move will help Baidu internationalize its driverless car business, while Uber will gain a proven partner to take on autonomous driving rivals.

Baidu is the latest addition to Uber's growing list of autonomous vehicle partners, which includes Waymo, Volkswagen, May Mobility, and Pony AI.

Uber and China's Baidu will partner to deploy thousands of Baidu's Apollo Go autonomous vehicles on the Uber platform across several international markets outside the U.S. and mainland China, the companies said on Tuesday.
