CONFERENCE ON DISARMAMENT CD/652 20 August 1985 Original: ENGLISH Sweden A comprehensive approach for elaborating regimes for chemicals in a future chemical weapons convention For the purpose of the Convention the relevant chemicals have in CD/559 been divided into five categories, i.e. super-toxic lethal, other lethal and other harmful chemicals, key precursors including key components for binary and multicomponent chemical systems for chemical weapons, and, precursors. This has proved to be a very useful categorization. However, attempts to apply one and the same set of measures to all relevant chemicals in each one of the five categories have failed. There is now a growing recognition that the diversity within a category and the different purposes for which these chemicals are produced need to be taken into account when elaborating the measures to be applied in order not to hamper the development of the peaceful chemical industry while at the same time ensuring that chemicals are not produced for chemical weapons purposes. There is also concern that one and the same chemical might be subject to qualitatively different measures depending on the purpose of its production and that this might create "loopholes" in the Convention. Time has therefore come to refine the concepts somewhat and to look for alternative ways of structuring the relationship between the categories of chemicals and the measures to be applied to them. This paper suggests an alternative approach for the elaboration of regimes of measures to be applied to the different chemicals involved. This approach allows for bringing together chemicals from different categories under one and the same regime, as well as for applying different regimes to different chemicals within one and the same category. This could be achieved through a regrouping of 
**Analysis**
The text discusses the development of a chemical weapons convention and the need for a comprehensive approach to regulating chemicals. It highlights the challenges of applying a one-size-fits-all approach to different types of chemicals and suggests an alternative approach to structuring the relationship between categories of chemicals and measures to be applied to them. The text does not explicitly mention economic development, natural resources, or environmental concerns, but rather focuses on the regulation of chemicals for weapons purposes.
