Compliance mechanisms and their implementation: the contrast between the Biological and Chemical Weapons Conventions

Abstract

ABSTRACT The 1993 Chemical Weapons Convention (CWC) and the 1972 Biological and Toxin Weapons Convention (BWC) are key components of the international arms-control landscape. Yet the two conventions differ widely, particularly in the ways that are available to treaty parties to resolve any questions about compliance with the treaties. Both contain language concerning consultation and cooperation, but the CWC also has extensive procedures available to investigate allegations of noncompliance. This article reviews these differences in the conventions and explains, in part, how and why they came about. The Organisation for the Prohibition of Chemical Weapons (OPCW) has engaged in several consultations regarding compliance issues, but the OPCW publishes virtually nothing about the topics of the consultations or their frequency, findings, or conclusions. An exception, perhaps, is the OPCW’s work regarding Syrian use of chemical weapons (CW). Moreover, thus far, no treaty party has called for a challenge inspection to officially investigate perhaps the most serious allegations of treaty violations: Syrian and Russian alleged use of CW. The BWC states parties conducted one formal consultation raised by Cuba, alleging that the United States dropped biological agents on the island nation from airplanes to cause an animal epidemic. The consultation reached no official conclusion. The article goes on to praise the work of Raymond Zilinskas debunking the allegations through a careful scientific review of the Cuban claims. The article discusses the consequences of secrecy surrounding the CWC consultation process and laments that the BWC does not have the institutional capacity to carry on the type of analysis that Zilinskas undertook discrediting the Cuban allegations.
