ASEAN Environmental Legal Integration: Sustainable Goals? is a contribution to the Integration Through Law: The Role and the Rule of Law in ASEAN Integration series, a project undertaken by the Centre for International Law at the National University of Singapore. The Association of Southeast Asian Nations ("ASEAN") was established in 1967 as a platform for five of the original ASEAN Member States ("AMSs"), Indonesia, Malaysia, Philippines, Thailand and Singapore, to promote cooperation towards peace, progress and prosperity in the region. In 2007, the AMSs, by now expanded to include Brunei, Cambodia, Laos, Myanmar and Vietnam, signed and ratified the Charter of the Association of Southeast Asian Nations, 20 November 2007 [ASEAN Charter], and created a formal legal and institutional framework for ASEAN.
