The Economist published a mind-blowing graphic depicting the migration of Chinese and Indian people around the world. The asses that “more Chinese people live outside mainland China than French people live in France, with some to be found in almost every country. Some 22m ethnic Indians are scattered across every continent.” More so, they emphasize that even though Diasporas have been a part of the world for millennia; their size and the ease of staying in touch with those at home are making them matter much more with the emergence of social network online technologies.
Now, this is once again part o the large “discourse of newness” that embeds great part of current mainstream history. This is something that has been denied and discussed by Prof. Adam McKeown in the article “Article: Global Migration, 1846–1940” who claims after doing a extensive research of migration from China and India during the 19th Century that the amount of immigrants and the global effect it had is comparable (and at some points superior) to the more known Atlantic migration from Europe to America. I strongly suggest you checking the Article by Prof. McKeown an check also Dr. Dirk Hoerder great book titled: Cultures in Contact in case you are interested in this subject.
