The paper theorises fragility of regional solidarities in light of the emerging ways in which two Arabian Gulf states, Bahrain and Oman, are undertaking their transition to a knowledge economy. The paper shows ways in which regional symbolic solidarity goals of common economic and educational development in the Gulf region are challenged by locally focussed priorities at the level of each nation state. These findings carry important theoretical implications as the time of transition to a knowledge economy seems to drive readjustments in thinking about what the 'Gulf-wide unity is for', prompting its repositioning from an alliance established to protect and facilitate regional development to a means supporting local ends. The paper therefore challenges the spatial focus in some theoretical frameworks used in analyses of the sociology of regional solidarities and calls for the need of temporal lenses in such analyses.
