On 2 December 2016, the Centre for International Law (CIL), ASEAN Secretariat (ASEC), and the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) successfully co-organised a Workshop on Treaty Management in International Organisations: Lessons Learnt and ASEAN Practice. The Workshop, which took place in the ASEAN Secretariat in Jakarta, was attended by nearly 70 representatives of the Committee of Permanent Representatives (CPR), the ASEAN Senior Law Officials, and the ASEAN Secretariat. The Workshop offered perspectives on the treaty management practices of ASEAN, the Council of Europe (CoE), and the International Atomic Energy Agency (IAEA) and discussed domestic practices of the UK, Singapore, and Thailand. The Workshop aimed to identify best practices in managing treaties in order to enhance treaty management practices in ASEAN. The Workshop report is forthcoming.
