This book tries to integrate the different arrangements devised in the MTS for small and large NMEs into one analytical framework and explores two sets of rules (GATT/WTO-minus and GATT/WTO-plus) along three historical stages (shaping, weakening and strengthening). The focal point of this book is to uncover the composition and structure of the NME treatment in the MTS, its evolving logic and process, and the nature and trend of the political-economic relations between NMEs and the MTS.
