Approximately 12 million Africans were shipped to the Americas during the Atlantic slave trade from 1492 to 1888, with 11.5 million of those shipped to South America and the Caribbean. Brazil was the largest importer in the Americas, with 5.5 million African slaves imported, followed by the British Caribbean with 2.76 million, the Spanish Caribbean and Spanish Mainland with 1.59 million Africans, and the French Caribbean with 1.32 million. Today their descendants number approximately 150 million in South America and the Caribbean. In addition to skin color, other physical characteristics such as facial features and hair texture are often variously used in classifying peoples as black in South America and the Caribbean. In South America and the Caribbean, classification as black is also closely tied to social status and socioeconomic variables, especially in light of social conceptions of "blanqueamiento" (racial whitening) and related concepts.

In southeast Asian colonies, such as Hong Kong, child labour such as the Mui Tsai (妹仔), was rationalised as a cultural tradition and ignored by British authorities. The Dutch East India Company officials rationalised their child labour abuses with, "it is a way to save these children from a worse fate." Christian mission schools in regions stretching from Zambia to Nigeria too required work from children, and in exchange provided religious education, not secular education. Elsewhere, the Canadian Dominion Statutes in form of so-called Breaches of Contract Act, stipulated jail terms for uncooperative child workers.

What did the Canadians do to children that did not wish to work?
Answer:
stipulated jail terms
