The triangular transatlantic slave trade involved Europe (specifically England/Britain), West Africa, and the Americas. The route carried manufactured goods from Europe to Africa, enslaved people from Africa to the Americas, and raw materials (sugar, tobacco, cotton) from the Americas back to Europe. China, Japan, Italy, Switzerland, Belgium, and France were not the primary participants in this specific triangular trade pattern - the dominant European nations were Britain, Portugal, France, and the Netherlands.
