In today's competitive economic environment, countries benefit from working together through regional integration projects. This helps them access resources and markets more effectively. Economic integration involves countries forming strong economic connections and sharing work based on their economic similarities. This process includes creating a unified market, aligning trade conditions, and forming economic unions. Developed regions like Western Europe and North America have successful integration models. Ukraine is considering joining either the European Union or the Customs Union. The choice of economic integration is crucial for Ukraine's future.
