In 2005, the UN General Assembly identified solidarity as one of the basic and universal values that should be the basis of relations between nations in the 21st century, and in this regard decided to declare December 20 of each year as the International Day of Human Solidarity.
The Sustainable Development Agenda focuses on people and the planet, supported by human rights and global partnership to lift people out of poverty, hunger, and disease. It is based on global cooperation and solidarity. The International Day of Human Solidarity is a day to celebrate our unity in diversity, remind governments to uphold their commitments to international agreements, raise awareness about the importance of solidarity, and promote discussions on ways to support solidarity for achieving sustainable development goals, including poverty eradication. Solidarity is identified as one of the fundamental values of international relations in the Millennium Declaration, and strengthening international solidarity is necessary in the context of globalization and growing inequality. The concept of solidarity has been defined by the United Nations since its inception, and the organization relies on solidarity to promote peace, human rights, and social and economic development. The World Solidarity Fund was established in 2003 with the aim of eradicating poverty and promoting human and social development in developing countries, particularly among the poorest segments of their populations.
