In classical times, the Roman Empire took slaves from all over... you might find a Briton for sale in an Egyptian market or vice versa, and you would certainly find both in Rome. In later eras, countless Africans were shipped across the Atlantic to the Americas, forever influencing the population demographics there. And even today, far more people are moved from country to country to serve as legal or semi-legal unfree labour than we would like to think.
Although there are various other considerations, these flows of trade mostly follow the laws of supply and demand - from poorer and colonial countries to richer and imperialistic ones. Of course, such countries often have ways of "domestic production" of slaves as well. And especially when slaves have ways of rising to freedom or even citizenship, foreign imports can be the foundation of new and lasting threads in a country's ethnic and cultural tapestry.
So, in a world much like ours, but where chattel slavery is as omnipresent as capitalism and slaves as common as cars... where would they come from, and where would they go too? Which countries would have larger or smaller slave populations (absolute or relative)? How would imports compare to local-bred descendants or former citizens enslaved for crime or debt? Would slaves of different origins tend to take different roles, fetch different prices, be more or less likely to achieve manumission? And what effect might this have on global population dynamics?
Well, those are a few questions - discuss whichever take your fancy.
