Google has faced sharp criticism, including from its own employees, for its efforts to rebuild an internet search presence in Chinaafter quitting the country eight years ago over censorship issues.

for Google’s corporate parent, Alphabet, the opportunities in the world’s largest internet market may be too good to resist. And the full scope of the company’s interest in China now appears to be broader than just internet search.

The latest hint came from Waymo, the driverless-car company that was spun out of Google in 2016. Chinese media noticed this week that the business had quietly registered a Shanghai subsidiary in May, suggesting that it wants a piece of an industry that the Chinese government has made a priority.

Unlike Google, Apple runs its own app store in China, heeding government directives about the kinds of apps that can be available to Chinese users. Microsoft and Amazon offer cloud computing services, working with local partners and following strict controls on how customers’ data is stored.

Baidu, maker of the country’s leading search engine, has made its autonomous-vehicle software platform available to dozens of local and foreign companies. SAIC Motor, China’s largest carmaker, is working with the e-commerce titan Alibaba. BMW and Daimler have received permission in China to test their own self-driving vehicles.
