As great power politics are regarded as trend setters in international relations(IR), most contemporary IR studies often neglected small states’ foreign behaviors. However, after the end of the Cold War, bipolar confrontation of great powers no longer existed, attentions began to turn to small states in the realm of international relations. The author argues that, with the help of proper design of methodological approach, the extent of small states’ external influences may be evaluated. For small European states, alternative, rotation, profession, and alliances are different categories that could shape the states’ external influences vested in EU’s institutional design. Moreover, social character and role-playing theories are also helpful for the explanation of state’s social position; namely, the roles of pace-setting, foot-security external influence model and the case study of fight against cigarette dragging or fence-sitting. Through the lens of small states non-traditional smuggling in Lithuania, we argue that small states may have their influences in regional integration and beyond.
