There was no lack of large scale trade with the East. There was actually a large scale trade network in Africa that people never seem to talk about. Kanem-Bornu was a large empire in the east, which controlled trade between Central Africa up to Libya and Egypt. So that kingdom traded goods between the people of Egypt and the Bantu people to the South and Southeast. The Hausa people were long distance traders that took goods from Kanem-Bornu to places like the Empire of Mali and back from the Empire of Mali to Kanem-Bornu.
Are we gonna compare that trade to what the Europeans and Muslims had? I mean Chinese plates and gunpowder were taken from the east and worked on in the west. The advent of gunpowder combined with the near constant warfare in Europe is what created the technological advances that sparked the west to conquer much of the world.
Or am I off base here?
