Basically Chinese authorities from what I believe wanted to generate a league that also had homegrown players, up to a point MLS was a retirement home but is now producing players who play in the top leagues in Europe.
This is more like a semi permanent IPL, I assume the reason they are swooping on freebies is not to inflate the market for Newcastle but players will wind up their contracts if they see this league fluttering it’s eyebrows.
I assume the aim is in two directions one a super league that has their teams competing with the likes of Man City and Newcastle amongst others or to build a league outside of that but as you said it’s hard to do.
You’ll get teams with defences that are atrocious and Ronaldo up top.
I don’t know about Saudi but Qatar is considered one of the least desirable deployments in the Air Force. Everyone I know who has gone there absolutely hates it.
