Abstract
The universalization and full realization of the objectives and goals of the United Nations 2030 Agenda for Sustainable Development can be called into question by the significant drop in international funding available to support developing countries. This situation may be worsened by the effects caused by the COVID-19 pandemic and the consequent increase in nonregular cooperation programs, based on humanitarian and emergency actions. The promotion of horizontalization strategies for the Sustainable Development Goals (SDGs), considering interventions with a transversal nature, in a 360° view, which encourages the promotion of strategic alliances, multisectoral and multidimensional partnerships as well as shared financing mechanisms, appears as a credible hypothesis to assure the commitment with sustainable development. The article addresses some perceptions of multilateral organizations, namely within the scope of the United Nations System and Bretton Woods institutions, and how the strategic development cooperation instruments created by Community of Portuguese Speaking Countries may contribute to boosting post-COVID-19 cooperation scenarios aligned with the accomplishment of the SDGs in this community.
