The right to development, both an individual and collective human right applicable to all individuals and peoples, is a universal human right that pertains to all people across all countries without distinction based on race, color, sex, language, religion, political or other opinions, national or social origin, property, birth, or other status. Furthermore, in the contemporary era, the issue of "sustainable development" has gained prominence. Sustainable development is defined as development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs. However, development cannot be achieved without financial resources. Undoubtedly, money is one of humanity's most significant inventions, essential for the development of nations. Thus, securing financial resources and employing diverse financing methods are critical tools and prerequisites for countries to achieve economic growth and realize their broader development goals. In this context, the United Nations has undertaken numerous initiatives to provide a framework for this issue and has adopted relevant documents. This article, using a descriptive-analytical method and drawing on library resources, examines the relationship between financing and the expectations of national markets and investors on one hand, and the priorities of the right to development on the other, within the framework of key UN documents. In this context, the importance of sustainable financing for achieving equitable and sustainable development is analyzed, and the roles of international financial institutions, global financial markets, and governments are evaluated, with recommendations provided at the conclusion.
