Which is ironic because the private entrepreneurs on the mainland are extremely good at marketing themselves. There should be incentives for the younger, more global generation to work for the government.
It's a bit OT but I'd guess there just isn't much money offered by the government to do more overt propaganda.
Russia and US put a lot of money, they employ and pay salaries to entire groups of ppl like operation earnest voice for example just to pretend to be pro government people online. I remember reading, megacompanies in US (which are all aligned with the govt) actually employ far more bots than the govt itself, so there's a lot of outsourcing or private use going on.
China built it's own net with it's own rules and not USA rules. So they mostly don't need to deal with the western stuff. That means theres not much incentive to touch English speaking spaces. China has after all only recently expanded to truly global force projection.
Now is a good time to start engaging with English speaking audience, which include many who would be strongly pro-China, such as Russian emigrants, Iranians etc.
China, or more accurately, "NGOs of Chinese origin" and "private companies" can form alternative and general news sites, with the goal to excaberate tensions in the west, weaken their political resolve and spread political thought.
I think as China now moves towards seeing the West as an enemy, such initiatives will be formed, and there should be many talented young people who would wish to take such a role on themselves.
Most importantly, the CPC needs to pay high salaries for them, you get what you pay for.
