While Uber Technologies Inc. is trying to dig out from scandals and curtail losses, its former China rival, Didi Chuxing Technology Co., is spending billions of dollars on other startups around the world.

Didi recently announced investments in three ride-sharing apps in as many weeks: Careem in the Middle East and North Africa, Taxify in Europe and Africa and Grab in Southeast Asia. Early this year, Didi invested in 99, a ride-sharing company in Brazil. It’s also put money into Lyft Inc. in the U.S. and Ola in India.
