Wang and Sun worked together to operate U.S. News Center, a website that purported to be a news source for the local Chinese American community. Wang and Sun received and executed directives from PRC government officials to post pro-PRC content on the website.
For example, in June 2021, a PRC official contacted Wang and other individuals via the WeChat encrypted messaging application with pre-written news articles, including a PRC official-written essay in the Los Angeles Times that stated: “China’s Stance on the Xinjiang Issue – There is no genocide in Xinjiang; there is no such thing as ‘forced labor’ in any production activity, including cotton production. Spreading such rumor to do defame China, destroy Xinjiang’s safety and stability, weaken local economy, suppress China’s development[.]”
Minutes later, Wang posted the article on her own website and responded to the PRC official with a link to the article on her website. The others in the group chat did the same. The PRC official responded: “So fast, thank you everyone.” “
That's certainly a way to describe WeChat.
It's very clearly labelled as an official response from the Chinese government. So it's what the people they're accusing have to say, and that's why they published it.
Whether or not to believe them is left to the reader.
If you accuse someone of something in print, you should at least give them the opportunity to refute it.
