"Strengthening the UMA is seen as a counter to the dominance of the Gulf Cooperation Council (GCC) – an organization encompassing six oil-rich Gulf Arab states – which has tried to exert its influence over north Africa in recent years." -- from: http://english.al-akhbar.com/content/tunisia-seeks-revive-maghreb-union
Whatever you may make of that claim, this is going to prove to be an interesting time post-Qaddafi, especially since Morocco will be hosting the Executive Council of Foreign Ministers of CEN-SAD in June in that country. (check: http://www.afriquejet.com/maroc-cen-sad-reunion-du-conseil-executif-en-juin-2012013032457.html).
It's good to know that the CEN-SAD HQ will remain in Tripoli -- as will the Sahelo-Saharian bank. I feel that big things are coming for dynamising North Africa.
