The XVII Annual Session was held on 8-9 May 2018. The theme of the conference was A Divided World.
The XVII Annual Session of HELIMUN was the largest conference so far (again), this time with over 400 delegates, chairs, judges and advocates participating from multiple different schools, including, but not limited to, Kulosaaren Yhteiskoulu, the Anglo-Amrican School of Moscow, Mattlidens Gymnasium and Espoo International School. The delegates Were extremely well prepared for the conference, the chairs were astonishingly good, and most importantly, the entire conference functioned exceedingly well as a whole.
