This chapter discusses regional systems of human rights protection by surveying the human rights standards adopted and institutions created to interpret and enforce human rights in different regions. The central focus of the chapter is the convergences and divergences between regional human rights systems in standard settings and institutional mechanisms, in particular, when compared to standards and institutions in place at the level of the United Nations. The chapter concludes with a discussion of future prospects for interactions between regional human rights systems, in particular, in the light of developments undertaken by the League of Arab States and the Association of Southeast Asian Nations.
