Facebook Inc. said Tuesday that it struck data partnerships with at least four Chinese electronics firms, including Huawei Technologies Co., a telecommunications-equipment maker that U.S. officials view as a potential tool for state-sponsored spying.

The four partnerships are among the roughly 60 that Facebook struck with device manufacturers starting in 2007 so they could recreate the Facebook service on their devices, a Facebook spokeswoman said. As of Tuesday, more than half of those partnerships have been wound down, the spokeswoman added.

The social-media company said it plans to wind down its data-sharing partnership with Huawei by the end of the week. It isn’t clear when Facebook will end partnerships with the three other companies: Lenovo Group Ltd. , the world’s largest personal-computer maker; Oppo Electronics Corp., a smartphone maker; and Chinese electronics conglomerate TCL .

Facebook officials defended the decision to work with Huawei and said that no data belonging to Facebook users was saved on Huawei servers. Facebook had a manager and an engineer review the apps before they were deployed to ensure the data wasn’t saved on company servers, the Facebook spokeswoman said.
