This chapter explores altruistic commitments that are specifically between developed and developing countries. In particular, an emphasis is placed on the right to development, official development assistance (ODA), the right to food and particular aspects of the international economic order, as well as the special role played by the principle of solidarity in this context. Indeed, development is central to the contemporary international legal order. As such, this chapter explores the various instruments, institutions and processes that are directed at furthering the cause of development by facilitating the transfer of resources from developed to developing countries.
