During the opening of the 2026 session of the Special Committee on Decolonisation, UN Secretary-General António Guterres emphasized the urgent need for the complete decolonisation of Western Sahara and 16 other territories still impacted by colonial rule. He highlighted that this call for decolonisation is a continuation of the UN's mission to address colonial legacies, which began over sixty years ago. Guterres pointed out that the issues stemming from colonialism continue to have a significant influence on global politics and society, affecting economic structures and perpetuating inequalities.

Guterres described colonialism as a historical injustice that has left lasting scars, impacting economic opportunities and feeding into systemic racism and social exclusion. He noted that the effects of colonial exploitation are evident in the exclusion of these territories from decision-making and development processes, reminding attendees that the UN was founded to foster equality among nations rather than perpetuate hierarchies of power. The call to action serves as a reminder of the challenges that still persist in achieving complete sovereignty for nations under colonial rule.

In addressing the issue of decolonisation, Guterres urged member states to renew their commitment towards ending the unfinished business of colonialism, reinforcing the UN's mission to ensure equality and representation in the global landscape. This appeal not only targets the political scenarios of specific territories but also aims at rectifying historical injustices that continue to disadvantage certain groups, thereby pushing for a more just and equitable global society.
