Prior to the “Arab Spring” movement，the EU policies in the Middle East and North Africa were mainly featured by institution construction. A sequence of projects ranging from Europe-Mediterranean Partnership，European Neighborhood Policy to Mediterranean Union were implemented but failed to realize the goal of prosperity and stability in the region. Since the “Wave of Democratization” began to sweep in the Arab World，the EU and its member states have immediately adjusted their policies by supporting the “regime changes” in some countries，adopting hardline foreign policies and utilizing various strict sanction tools. The overall effect，however，remains poor，in that the perimeter security still awaits consolidation. Currently，the EU has basically a-bandoned the intervention “impulse” and returned to the tradition of political dialog.
