Beijing, Jun 6 (AP) Chinese phone maker Huawei said today it has never collected or stored Facebook user data, after the social media giant acknowledged it shared such data with Huawei and other manufacturers.

Huawei, a company flagged by US intelligence officials as a national security threat, was the latest device maker at the center of a fresh wave of allegations over Facebook's handling of private data.

Chinese firms Huawei, Lenovo, Oppo and TCL were among numerous handset makers that were given access to Facebook data in a "controlled" way approved by Facebook, the social media company's vice president of mobile partnerships, Francisco Varela, said yesterday.

Varela's statement came after The New York Times detailed how Facebook has given device makers deep access to data, including work history, relationship status and likes on device users and their friends.

In a follow-up report, the Times said the recipients of Facebook data included Huawei and other Chinese firms that have long been labeled a national security threat by Congress. Facebook said it would end its data partnership with Huawei by the end of this week.

While Facebook is banned in China, the government could have had access to user profiles elsewhere, including those of Americans with Huawei phones. However, there's no evidence that happened. Facebook said it helped design and approved Huawei's app, so it knows the data remained on users' phones and wasn't transferred to Huawei.

Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, said the news raises legitimate concerns and wanted to know how Facebook ensured data was not transferred to Chinese servers.

Huawei spokesman Joe Kelly said in a text message today that the arrangement was about making Facebook services more convenient for users. Facebook said it granted smartphone access to users' data before mobile apps became popular, as a way of making its service work on a broad range of devices.

Device makers could then build their own software that incorporated Facebook functions, for things like messaging or posting photos. User would log into their Facebook accounts, allowing the phone software to pull in data from Facebook itself.

The partnerships were used for older phones to make Facebook work or at least work better, according to the company. Newer phones are more powerful and don't need such data sharing. Nonetheless, Facebook didn't get around to reviewing these partnerships until after the Cambridge Analytica privacy scandal developed.

Apple said it has worked with Facebook for years to let users share things on Facebook through iPhone and Mac apps. Apple said it used data pulled in from Facebook to let people post photos and other items on Facebook without opening the Facebook app. It ended that practice on the iPhone last September, although similar features persist on Mac computers.

Hua Chunying, a Chinese Foreign Ministry spokeswoman, declined to comment on the issue but said: "We hope the U.S. can provide a fair, transparent, open and friendly environment for Chinese companies' operation and investment."

The company, founded by former Chinese military officer Ren Zhengfei, has long denied that its products pose security risks even as it grew into the world's largest telecom equipment provider and a leading phone manufacturer — behind only Apple and Samsung.

Huawei and its Shenzhen-based rival ZTE have been the subject of security misgivings in the US for years, but they have come under particular scrutiny since the start of the Trump administration amid rising US-China tensions on a range of subjects.

The Pentagon in May banned the sale of Huawei and ZTE phones on military bases, four months after AT&T dropped a deal to sell a new Huawei smartphone. (AP)
