Global governance, international health law and WHO: looking towards the future.

The evolving domain of international health law encompasses increasingly diverse and complex concerns. Commentators agree that health development in the twenty-first century is likely to expand the use of conventional international law to create a framework for coordination and cooperation among states in an increasingly interdependent world. This article examines the forces and factors behind the emerging expansion of conventional international health law as an important tool for present and future multilateral cooperation. It considers challenges to effective international health cooperation posed for intergovernmental organizations and other actors involved in lawmaking. Although full consolidation of all aspects of future international health lawmaking under the auspices of a single international organization is unworkable and undesirable, the World Health Organization (WHO) should endeavour to serve as a coordinator, catalyst and, where appropriate, platform for future health law codification. Such leadership by WHO could enhance coordination, coherence and implementation of international health law policy.
