BEIJING (AP) — Uber Technology Ltd.'s main Chinese rival, Didi Chuxing, says it is acquiring the U.S. ride-hailing service's China operations, linking the companies in a business alliance after a costly battle for market share.

Monday's announcement marked a surrender by another foreign technology brand to intense competition in China. Yahoo and eBay also turned over local operations to Chinese partners or shut down.

Didi Chuxing said it would take over all of Uber China and operate it as a separate brand. In exchange, the company said, Uber will receive a stake in Didi Chuxing and Uber founder Travis Kalanick will join the Chinese company's board.

The two companies have suffered heavy losses as they fought to attract customers.
