The main focus of Nigeria's foreign policy since independence centers on
South- south cooperation
Sub-regionalism
Globalism
Afrocentrism
Correct answer is D
Since independence in 1960, Nigeria's external relations have been characterized by a focus on Africa as a region, focusing on fighting colonialism, apartheid, and the discrimination of black peoples in the African continent and elsewhere in the world.
A general word to describe this policy would be Afrocentrism, which is a cultural and political movement meant to positively reflect traditional African values and promote the history of Black people.
