Welcome to the conference on “Regional Integration and Security: Lessons from the European Union.” Regional integration has proven to be a powerful tool for promoting stability and security across diverse countries and regions. This conference aims to draw lessons from the European Union’s experience in regional integration and explore ways to apply these insights to other regions facing security challenges. Through discussions, case studies, and expert insights, we will examine the various dimensions of regional integration and its impact on security, ranging from political cooperation and economic integration to the establishment of shared institutions and norms. Join us as we explore the key factors that have contributed to the success of the European Union and discuss how these lessons can be applied to promote stability and security in other parts of the world. Together, let us uncover innovative strategies for achieving regional integration and fostering a more secure future.
