Could the signing of 'ASEAN Charter' be considered as an evidence of the organization's development corresponding to neo-realist's view of improving the lack of 'pooled sovereignty'?

Lack of pooled sovereignty
1. ASEAN Way
  1. fair-weather cooperation
  2. consensus-building platform
  3. non-confrontational bargaining
  4. informal mandate
ASEAN Charter
1. signed in 2007
2. legally binding document
3. consensus/unanimous vote
4. non-intervention/ integrity of sovereign right
5. techinical-related rules depending on member compliance
neo-realist view
1. ASEAN future
  1. ability to coerce = power
  2. Secreteriat vs. compliance
  3. shift to rule-based sys. required
  4. stronger binding rules
  5. power policed through sanctions
Constructivist
1. ASEAN future
  1. Trust trumps compliance
  2. constitutive norms, principles = ties
  3. degree of group cohesion, not coercion
