Self-driving tech company May Mobility is looking to bring its robotaxis to new international markets by teaming up with Chinese ride-hailing service CaoCao. The partnership, announced Wednesday, aims to bring "large-scale commercialization of robotaxi services" to more locations, starting in Europe.

As part of the agreement, the two companies will look into expanding commercial robotaxi operations and launch pilot programs in "key markets, including Europe." CaoCao will own the robotaxi fleet and operate services such as vehicle support and maintenance, while May Mobility's autonomous driving tech will power the self-driving fleet. 

May Mobility has previously partnered with ride-hailing companies Lyft and Uber to bring its robotaxis to cities including Atlanta and, soon, Arlington, Texas. Earlier this year, May Mobility expanded into Japan and says it's completed more than half a million commercial autonomous rides in the US and Japan. It currently uses hybrid-electric Toyota Sienna minivans equipped with its self-driving technology and aims to announce a new third-party vehicle platform later this year.

May Mobility's autonomous vehicle system relies on multi-policy decision making technology. The company says it "applies real-time, human-like reasoning to handle unexpected situations with AI-powered speed and precision." That allows the robotaxis to navigate real-world scenarios that spring up in the moment, which can be helpful as May Mobility enters new international markets.

Like other ride-hailing platforms, CaoCao is leaning into physical AI and self-driving partnerships. Last week, the company said it "plans to deploy a total of 100,000 robotaxis and 100,000 robovans" by 2030. Uber and Lyft have also collaborated with dozens of AV companies, including Waymo, Nuro and Tensor, as the self-driving space picks up steam.

"International expansion is a key direction for CaoCao's autonomous driving business," the company said in a statement. "Europe offers diverse real-world environments and strong potential for robotaxi commercialization. Through our collaboration with May Mobility, we aim to combine our strengths in operations with their leadership in autonomous driving technology to accelerate validation and deployment across different markets."
