On behalf of the European Commission and the Government of Norway, the Informal DSI Negotiators' Dialogue on the DSI MLM and its Cali Fund was organized by the DSI Informal Dialogue Partnership. The Dialogue was held at Hotel Martin’s Klooster in Leuven, Belgium, from 23rd to 25th September 2026. The Dialogue brought together over twenty key negotiators from all global regions, as well as some recognized experts and members from UN secretariats to elaborate outstanding issues related to the DSI multilateral mechanism (MLM) and its Cali Fund in preparation for CBD COP17. On the first day of the Dialogue (23rd September), attendees met with the participants of the preceding Stake- and Rightsholders' Exchange to present key messages emerging from DSI users and IPLCs and to explore possible pathways towards consensus ahead of COP17. Participants discussed whether contributions should begin before the COP18 review, how far obligations should extend along value chains, possible bases for proportionate industry payments, the content and national recognition of certificates, the interface between the MLM and national ABS requirements, and how to balance legal provenance and transparency with research and open access. The negotiators'dialogue showed substantial convergence on the need to move pragmatically towards implementation, while important differences remain over the pace, parameters and safeguards. The solution pathways developed during the dialogue could provide possible ways to bridge these differences.
