Negotiating access and benefit sharing (ABS) under the Convention on Biological Diversity (CBD) with a view to mutual supportiveness with other international agreements is a challenging task. This report highlights many key interfaces that must be taken into consideration if a new international regime is to be mutually supportive with already established international commitments. The document deems that there are good arguments for a broad and inclusive international regime on ABS. Still, it will need to take into account the special characteristics of the different sub-categories of genetic resources. A proper regime would entail having general provisions that apply for all sectors dealing with ABS sides, and sector-specific provisions that meet the specific features and needs of specific sub-categories of genetic resources.
