Cultural diplomacy is significant in international relations as it fosters mutual understanding and builds trust among nations through cultural exchanges, arts, and education. By promoting cultural ties, countries can enhance their soft power, improving image and influence without coercion. Cultural diplomacy can mitigate conflicts and promote cooperation on global issues, such as climate change and human rights. Engaging in shared cultural activities helps to break down barriers, enabling nations to navigate complex political landscapes more effectively, thus contributing to more harmonious international relations.
