International Cooperation for Development (CID) despite being considered an important instrument for peaceful coexistence and stability of the international system, has failed to achieve its main objective which is the economic and social development to reduce global poverty. To demonstrate the above, a distinction is made between cooperation and assistance, stating that the first occurs in symmetrical relationships in which the parties involved give and receive, while the second is called to respond to the interests of donors. Next, it examines the conflict between national interest and cooperation, to finally reveal how unproductive has been the CID in solving the problems of underdevelopment, because its actions have been ineffective and inadequate, which can be seen with the humanitarian crisis lived in the planet today, that require an analysis from the social and political sciences standpoint and from the interdisciplinary view that characterizes bioethics as the ethic of the XXI century.
