Abstract
The last few decades has seen the explosion in international flows like monetary flows, flows of goods, human flows. This is part of a wide movement that has kept on increasing since the end of World War II, and one that has later been called globalization. In this phenomenon, two new major actors have entered the game, China and India, representing nearly half the global population. Once great civilizations, they have spread around the world, as merchants or as slaves, sowing the seeds of diasporas, that is the seeds of people who, although far away, keep vivid memory of ancestors. And this memory is all the more vivid as China and India are two gigantic cultures. We will try to find out what impacts these two diasporas have had on the regions they have penetrated, on themselves, and eventually if it could have an impact on the very homelands.
