Here's a graph from the New York Times on source countries for adoptions by American parents. The usual pattern appears to be that American agencies discover a country where orphans are poorly cared for, kind-hearted Americans looking to adopt offer to take unwanted children off their hands, the frequency builds, but then generates a nationalist backlash of shame and anti-Americanism that encourages the source countries to crack down on adoptions by Americans and (hopefully) start being more civilized toward their own kids. 

As tumultuous as these cycles must feel to all concerned, I would say the process generally represents progress.
