Spain Youth Model United Nations (SYMUN) is a project co-organized by the Common Action Forum and the United Nations and International Law Association (ANUDI) at Carlos III University of Madrid. It aims to empower young students, to bring them closer to public institutions, to foster their critical thinking, to promote sustainable values and to enhance dialogue and cooperation as a means to confront contemporary challenges. Within the Model United Nations (MUN) framework, a simulation where students from all over the world come together to step into the shoes of diplomats from the UN member states, SYMUN will bring together around 400 young and bright high school students from diverse backgrounds and allow them to debate the dynamics of international relationships in a thoroughly multicultural environment.
