US tech giant Apple has raised its stakes in China by investing $1 billion in a ride hailing app Didi Chuxin, the single largest investment received by the Chinese cab-service company.

Didi said that it has received $1 billion in strategic investment from Apple.

The investment from Apple is the single largest investment Didi has ever received. The investment is considered significant as Didi rivals US taxi hailing app Uber, China Daily reported.

Apple is among a group of Chinese and international institutions that are bankrolling Didi’s ambitious expansion plan in its latest fundraising round.

Through this investment, Apple has become a strategic investor in Didi, and joins Tencent, Alibaba and other key supporters to help further Didi’s mission of building a data—driven ride—sharing platform to serve millions of Chinese drivers and passengers, the report said,.

“The endorsement from Apple is an enormous encouragement and inspiration for our four—year—old company. Didi will work hard with our drivers, riders and global partners, to make available to every citizen flexible and reliable mobility choices, and help cities solve transportation, environmental and employment challenges,” Cheng Wei, founder and CEO of Didi, said.

“Didi exemplifies the innovation taking place in the iOS developer community in China,” Tim Cook, Apple’s CEO said.

“We are extremely impressed by the business they’ve built and their excellent leadership team, and we look forward to supporting them as they grow,” he said.

Building on its data mining and analysis capabilities, Didi said in a statement that it records over 11 million rides a day on its platform, serving close to 300 million users across over 400 Chinese cities with a diverse range of mobile technology—based transportation options.
