A US teenager's TikTok video clip accusing China of putting Muslims into "concentration camps" has gone viral on the Chinese-owned social network.
Feroza Aziz later tweeted that TikTok had blocked her from posting new content, as a result.
"TikTok does not moderate content due to political sensitivities," a spokesman told BBC News.
Although, Douyin, the Chinese version of the app, on which Ms Aziz's posts would not have appeared, is politically censored.
As an additional measure, it had then blocked her smartphone, on 25 November, but that too had been unrelated to her posts about China.
For its part, the Chinese government has consistently said the camps in question offer voluntary education and training, despite evidence to the contrary.
She has tweeted that TikTok has given her a one-month suspension and said that "China is terrified of the news [about the camps] spreading". »
