We recognize that colonialism has led to racism, racial discrimination, xenophobia and related intolerance, and that Africans and people of African descent, and people of Asian descent and indigenous peoples were victims of colonialism and continue to be victims of its consequences. We acknowledge the suffering caused by colonialism and affirm that, wherever and whenever it occurred, it must be condemned and its reoccurrence prevented.
