I highly doubt there is some hereditary trait that makes Asians better at running factories than those other countries. It's more likely that given the tremendous amount of manufacturing that's been pushed to those countries, they have had ample practice to become leaders at the process.
If you look holistically at what happened, you're more likely to find why so much moved to Asia. Geographically speaking there may have been closer low-wage countries, but distance alone does not determine where you can build appropriate facilities.
Geologically, China has access to large ports, allowing large amounts of tonnage to flow in and out. You have a generally easy path from China to California. Eastern Europe is out because you can't easily ship to and from. Similarly, jungles and mountains in Latin/South America and Africa keep large manufacturing bases from being built. Africa lacks sufficient ports - its largest ships 1/10 the tonnage that Shanghai does.
At a local political level, you have governments willing to subsidize manufacturing and tolerate certain working conditions that other governments wouldn't.
From an international perspective, you have incentives to bring capitalism to the borders of previous socialist countries as a destabilization measure (large increases in US-China trade in the 80s).
