The past, traditions, religion: these are all elements that make up a person’s cultural environment. Culture is not only in the roots of the individual behind the diplomat, it is the negotiating tool on the negotiating table, it is the key to peace. In the complex environment in which humanity finds itself, cultural diplomacy plays an essential role in international relations. By promoting mutual understanding and social cohesion, it often puts itself in the interlocutor’s shoes, sees the discussion from a cultural perspective and reaches a compromise based on respect for the customs of both sides. For example, UNESCO initiatives aim to promote cultural diversity. Another strength of this area of diplomacy is its social benefits. As it fosters cultural and creative industries, it opens up new positions on the labour market and generally strengthens the economy. Furthermore, in terms of conflict resolution and post-conflict rehabilitation measures, it could play a crucial role as it promotes peaceful negotiations, dialogue and cooperation. This also leads to soft power: cultural assets can serve as it could enhance the image of the respective state on the global stage. However, as in all aspects of life and politics, there are certain weaknesses of cultural diplomacy. Its repercussions can mainly be seen in the long term, which precludes its use in situations requiring immediate action. Since states are equal before international law, they should also be equal in cultural diplomacy. Unfortunately, there is the risk of so-called ‘cultural imperialism’ in which one culture dominates over others. As for the political use of this area, it could sometimes be misused and thus diminish its credibility. All this considered, cultural diplomacy is a complex but essential field of foreign policy. It is the bridge between human nature and the geopolitical scenario.
