Abstract:At its early stage, the diplomacy of Soviet Union featured strong revolutionary idealism and it was difficult to carry forward revolutionary diplomacy due to the lack of desirable practice environment. After World War I, the changes of international pattern and world revolutionary situation urged Lenin to abandon former “entrepreneurial plan”, combine revolutionary theories with new practical experience, apply the general rules and practices of international relations to develop the relations with bourgeois states, establish new strategic framework and adjust diplomacy layout practically. After 1921, the diplomacy of Soviet Union changed its initial tendency of refuting all traditional diplomacy forms and practices, started to turn to tradition consciously, and evolved towards traditionalism and nationalism. Factors such as the international role positioning of Soviet Union, strategic interests and diplomatic strategy measures diminished the influences of ideology and struck a balance tactfully between revolutionary ideal and realistic state interest and diplomatic traditions. This played an important role in improving the diplomatic status of Soviet Union and survival and development environment. Thus, diplomatic strategy targets of Soviet Union were able to be realized and strategic position improved gradually. The basic outline of diplomacy during the whole period of Soviet Union took shape preliminarily in this process.
