Russia's foreign policy has changed over the past 30 years through different stages, influenced by domestic and international factors, as well as the beliefs of Russian leaders. The main diplomatic theories shaping this policy are Westernism, Eurasianism, and Slavism. Despite changes, Russia has consistently aimed for great power status, focused on national security, sought international influence, used global mechanisms, and emphasized economic diplomacy. The current trend is towards Great Power Diplomacy, which is likely to continue in the future.
