Following the banishment of Donald Trump in his final weeks in office, Twitter’s moderation tool has again locked the official account for China’s US embassy, over a tweet about Uighur women that violated company policy against dehumanization.

Citing a study reported by state-controlled newspaper China Daily, the Chinese Embassy account, @ChineseEmbinUS, tweeted this month that Uighur women had been emancipated by government policy from being “baby making machines.”  

“We’ve taken action on the Tweet … for violating our policy against dehumanization, where it states: We prohibit the dehumanization of a group of people based on their religion, caste, age, disability, serious disease, national origin, race, or ethnicity,” a Twitter spokesperson said in a statement.

The ethnic Uighurs, a Muslim minority living in western China, have been repressed by the Chinese government for years, according to the United Nations, United States and United Kingdom.

China has repeatedly denied mistreatment of the Uighurs, most recently on Wednesday when its Foreign Ministry angrily responded to former U.S. Secretary of State Mike Pompeo’s characterization of Uighur policy as “genocide.”

Twitter removed the tweet and replaced it with a label stating it was no longer available.

The social media giant’s terms of service states that tweets that violate its policies are hidden, and the accounts are either locked or some features are temporarily limited. Users have to manually delete the tweets in question if they want the account to be fully restored.

The account for the Chinese embassy in the U.S. last tweeted on Jan. 9.

Ironically, Twitter, Facebook and Google are all banned in China.
