Regulation is about the control and restraint of private sector activities in the interests of the public good; in this case public security and the absence of violent conflict. The paper therefore attempts to identify the private sector activities that are of concern in conflict situations and assess whether there are relevant regulatory instruments to address these. There are in fact no comprehensive laws or regulations specifically dealing with the role of business in conflict, but rather a range of instruments and measures related to cross-cutting concerns such as human rights and corruption. An incipient regulatory framework for business operating in conflict situations is only just emerging. This paper attempts to make sense of this framework by mapping the issues and responses as a basis for making recommendations on how to fill the noted gaps.
