Yep, a professor of Marxism in a state-run Chinese university, definitely sounds very neutral. /s
Springer is an academic publisher, but that doesn't mean they agree with the viewpoints of every niche humanities publication in their catalogue. It's sort of like how Penguin offers both Das Kapital and Mein Kampf (with a disclaimer that I'm not calling anyone a Nazi).
Please don’t resort to calling everything that posits an alternate view propaganda.
Even when propaganda is true it's propaganda. Leftists are usually pretty good about acknowledging that, even.
