"Colonialism induced the African ironworker to abandon the process of extracting iron from the soil and to concentrate instead on working scraps of metal imported from Europe. The only compensation for that interruption would have been the provision of modern techniques in the extraction and processing of iron. However, those techniques were debarred from Africa, on the basis of the international division of labor under imperialism. As was seen earlier, the non-industrialization of Africa was not left to chance. It was deliberately enforced by stopping the transference to Africa of machinery and skills which would have given competition to European industry in that epoch."
