China slams Facebook for 'unfairly targeting' its biggest media companies

China said Facebook was unfairly targeting its biggest media companies on Friday after the network began attaching disclaimers to pages run by the country's state-controlled news outlets.

Foreign ministry spokesman Geng Shuang accused Facebook of selective enforcement and said he hoped the company would "abandon its ideological prejudice".

He told reporters during a daily briefing that any media agency operating in line with relevant laws of various countries should be treated equally.

Pages managed by news agency Xinhua and the fiery nationalist tabloid Global Times are now labelled "China state-controlled media", after a policy change by the world's largest social platform.

Facebook's definition of state-controlled media includes influence over editorial content as well as financial backing of outlets, said the platform's cybersecurity chief Nathaniel Gleicher.

"People should know if the news they read is coming from a publication that may be under the influence of a government," he wrote in a Thursday blog post announcing the new policy.

Relations between China and the United States have worsened on multiple fronts in recent months, with the two governments expelling journalists in tit-for-tat moves and trading barbs over the coronavirus outbreak and human rights

Facebook said it will add similar labels to pages and advertisements run by media outlets subject to editorial influence and financial backing by governments, including Russian state broadcaster RT.

The move comes with Facebook under scrutiny for failing for stem foreign interference in the 2016 US election, and after heated debate over how the network handles misinformation and inflammatory posts -- including from US President Donald Trump.
