 In 1967, Indonesia, Malaysia, Philippines, Singapore and Thailand founded the Association of Southeast Asian Nations (ASEAN). In the early 1990’s, five more states became members of ASEAN: Brunei, Cambodia, Laos, Myanmar and Vietnam. Southeast regionalism has indeed been the most difficult to summarise and conceptualise, because it has shaped up in an original way with respect to regional theories, showing a preference for de facto regionalisation rather than for de jure cooperation. Henceforth, the Association has been known for the highly informal 'ASEAN Way' of diplomacy. In November 2007, the Heads of State and Government of the member states signed the ASEAN Charter, which entered into force on 14 December 2008. By introducing a Charter, the Association has been given a more formal framework.  Normal 0 14 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tabella normale"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} The original version of this article did not properly acknowledged the work of Daniel Seah "The ASEAN Charter", published in Volume 58 (Issue 1, January 2009) of the International and Comparative Law Quarterly .
