Essentially the title.

What is the official publication of the Chinese Communist party? Does such a thing exist?

I am asking this because this article https://beta.ctvnews.ca/national/coronavirus/2020/9/7/1_5095060.html By the Canadian press left much to be desired in terms of what is the official stance of China on a Covid-19 vaccine is. It was extremely lacking on detail imo.

Where should I look to get the Chinese government line on things, Chapos?
