Diplomacy is a continuation of internal affairs, and the internal situation of a country will have an important impact on foreign policy. The current Russian-Ukrainian relations are clearly affected by the Ukraine internal situation.

Russia and Ukraine once lived together in Kievan The invasion of the Mongol armies set Russia and Ukraine on different paths of development. In the middle of the 17th century, Ukraine on the left bank of the Dnieper River (Eastern Ukraine) was incorporated into the territory of the Russian Empire. In the 18th century, the southeastern part of Ukraine also became part of the Russian territory? But western Ukraine has long been under the rule of Poland and Austro-Hungarian Empire . When the Union of Soviet Socialist Republics was founded in 1922, there were still more than 7 million Ukrainians living in Poland, Czechoslovakia and Romania.

After the outbreak of World War II , Soviet troops entered Poland from the east and occupied West Belarus and West Ukraine. After the war, Galicia, Volyn, North Bukovina and the Transcarpathians officially separated from Poland, Romania and Czechoslovakia and merged into the Ukrainian Soviet Socialist Republic, thus achieving the historic unity of the territory of Ukraine. This checkered history has had serious repercussions for Ukraine. After becoming an independent sovereign state, significant differences in language, religion, and cultural affiliation between the east and the west have led to Ukraine’s lack of national identity, which directly affects Ukraine’s social life and its foreign policy.
