Diaspora relations operate laterally between diasporas, not vertically from origin to copy.

Evidence

The relationship between Caribbean cultures and their diaspora cannot therefore be adequately conceptualized in terms of origin to copy, primary source to pale reflection. It has to be understood as one diaspora to another. Here, the national frame is not very helpful. Nation-states impose rigid frontiers within which cultures are expected to flourish. — Stuart Hall, Essential Essays, Volume 2, 840
