I'm literally just parroting what some international Chinese students I know said after I sent them the documents that were published. I don't speak mandarin, they told me it looked like a non native speaker (or at least writer) wrote some of them who looked like they had an okay grasp on the language for someone recently writing and they told me the only way that would happen in an official capacity is in low level local cadre/party reports since those could have people who may speak mandarin/understand it but not write it well.
