As part of the arrangement, Baidu will introduce thousands of its Apollo Go autonomous vehicles on Uber’s platform in areas outside of China and the United States.

Uber just announced a deal today with the company that runs one of the largest robotaxi fleets in China, as the ridehail giant nears its goal of becoming the world’s ultimate autonomous vehicle clearinghouse.

In China, backers of Uber China will own 20 percent of the merged operation. Internationally Didi will have a $1 billion stake in Uber Global, the ride-sharing app's parent company.

Tesla expanded the ‘geofence’ for its robotaxi pilot service in Austin, Texas, less than a month after its launch.
