I don't think this is it. The clubs don't want to let the top players go because then there's no guarantee of the club's success (and by extension, the officials' promotions...). CVA probably doesn't mind if the top players go abroad, but individual clubs (Tianjin, jiangsu, etc) will not be happy.
is it a big deal to have the local, Chinese talent? Wouldn’t it be better to let in more foreigners, to allow players like LYY to go overseas
