International sanctions impact countries by limiting their economic growth and trade relations. These sanctions, typically imposed by governments or international bodies, aim to alter a nation's behavior or policies by putting pressure on its economy. Sanctioned countries may experience reduced foreign investment, currency devaluation, and shortages of essential goods. These effects can lead to social unrest, hinder development, and in some cases, push governments to comply with international demands. However, the effectiveness of sanctions can vary based on their implementation and the resilience of the targeted nation.
