Book 4

The Newly Industrialized Economies, or NIEs, is a title occasionally used in the Appleseed manga to describe a series of independent small countries in Southern Asia that are gradually emerging from poverty and embracing industrial revolution. In the Appleseed ID graphical encyclopedia, author Shirow Masamune points out, however, that these small states are still polarized in that they comprise evenly of both "orderly cities and sprawling slums."

Geographically, using a map in the Appleseed ID, most of the NIEs in question appear southeast of India, and appear to include Fiji, Cambodia, Vietnam, Thailand, the Phillipines, and possibly even the Maldives.
