Recurrence pattern: every year on December 4.

The International Day Against Unilateral Coercive Measures is observed worldwide every December 4. Established by the United Nations General Assembly in 2025, this day aims to highlight the impact of unilateral coercive measures on human rights. These measures, which include economic, financial, trade, or diplomatic sanctions imposed by one or a group of states, can significantly affect the targeted state's economy and civilian population. They often disrupt access to essential goods and services, leading to humanitarian consequences such as inflation and reduced public services. The UN urges member states to refrain from imposing such measures that violate international law, particularly those affecting developing countries. The observance serves as a platform for discussions on the legality and humanitarian impact of these sanctions.
