a) As far as marketing and exposure, you don't need to sign a Saudi player. There's already plenty of Saudi sponsorship in La Liga, and the marketing and publicity that goes with it. b) Regarding the Chinese example, you're not comparing like for like. These are well established international players, not unknowns in Saudi. There's no upside in their valuation for the local market by going to Spain. Salem al-Dossary is a star player in the richest club in Saudi. There's nowhere up for him to go regionally.
