Ads for websites and apps that use Facebook to promote their content are already banned in China, according to a report published on Tuesday.
The ban comes after a wave of recent protests that began in February to protest government corruption.
Facebook is also known for censoring news content that it deems objectionable.
The crackdown comes amid growing concern about the effect of Facebook ads on the economy and the spread of cyberattacks on businesses.
The Washington Post reported on Tuesday that the new ban is the first of its kind for a major social media platform.
Facebook says it’s working with Chinese authorities to “improve our policies on ads” that are published on the social network.
The Post said the new restrictions were not directly related to China, but that Facebook’s China office is now involved in investigating complaints about ads on its platform.
Chinese government officials have been increasingly frustrated with the way Facebook operates in China.
Facebook in February banned foreign sites that publish ads on Chinese sites and asked Chinese authorities for information about their advertisers.
The company also said it would limit foreign ads from appearing on its Chinese platform until it got assurances from Chinese authorities that foreign ads would be filtered out.
In the wake of the new crackdown, the company’s shares have dropped more than 50% in the past month.
In China, ads are viewed almost exclusively by China’s state-run media and by private groups such as pro-democracy groups.
Many Chinese say they want to avoid paying for ads from those groups, fearing they could be used to support the government.
Advertisers in China are also often forced to pay for content that appears on social networks such as Facebook and YouTube.
In addition to being banned from the mainland, some foreign publishers have also been blocked from the country.
Last year, Google removed advertisements from several websites, including the English-language news site The Guardian.
Facebook recently shut down the website of the Chinese news site Sina Weibo, where users share stories and photos of corruption and corruption-related incidents.
The Guardian and Google have both said they will review their policies to help prevent similar problems from occurring in the future.
