I personally feel that it wouldn't make much of a difference. Western media is so ingrained and a self perpetuating echo chamber is real hard for anyone else to take the initiative.What China needs is a few Western trained spin docters.
Is there any country not allied with the US that has a strong media presence?
China needs to have more echo chamber too and make sure they dominant the Chinese language news first then move onwards. I do agree there is a hell of a lot more they can do like RT or TRT in terms of getting more vocal.
