The globalized world we live in today is marked by economic dependance, which can be measured by the mutual cooperation of countries. As a result, the economy has also taken on a central role in diplomatic action over the years. The gap between traditional and modern diplomacy is getting weaker, since they often overlap. Economic diplomacy has gradually become a central activity of diplomacy and international relations. Economic diplomacy has been analyzed in the theoretical field, is understood as means of foreign policy. This also applies to the Republic of Croatia, a country with a long history of diplomacy. The authorities in the times of the Republic of Dubrovnik already recognized the importance of economic dependance and thus the intensification of economic relations between countries. In order to cooperate economically with other countries, Croatia has also developed a model of economic diplomacy with which it can protect its economic growth and development, while also positioning itself in the international environment. The Croatian Chamber of Commerce plays an important role with opening different Representative Offices all over the world. The aim of these operations is to promote Croatian enterpreneurs and attract foreign investment. The Croatian Chamber of Commerce has a great influence on the Croatian economy, especially because of its operations in third countries. Thus, operations of the Croatian Chamber of Commerce represent a bridge between the state and the economy, and due to its active participation in international markets, its operations are important for Croatian foreign policy and (economic) diplomacy.
