Economic sanctions impact international relations by serving as tools for foreign policy aimed at compelling behavior change in target nations. These sanctions can weaken a nation's economy, limit its access to global markets, and create diplomatic tensions. They may also lead to unintended consequences, including humanitarian crises or strengthening of nationalist sentiments. Sanctions can either isolate a country or, conversely, rally domestic support against perceived external aggression. In many cases, the effectiveness of sanctions hinges on their implementation, international cooperation, and the targeted country's resilience.
