NAM was founded during the collapse of the colonial system and the independence struggles of the peoples of Africa, Asia, Latin America and other regions of the world and at the height of the Cold War.
Its actions were a key factor in the decolonisation process, which later led to the attainment of freedom and independence by many countries and people and to the founding of tens of new sovereign states.
Throughout its history, NAM has played a fundamental role in preserving world peace and security.
The chairmanship of NAM will be built on three main priorities, among others increasing the effectiveness of the Movement to further enhance the reputation of the organisation on the global stage.
The other priorities are the promotion of the Bandung principles and the strengthening of the unity within the Movement.
