Soft power is “the ability of a nation to attract other nations to one’s side, to win the trust of international society, and gain a greater voice not through coercion but through obtaining understanding, appreciation and support for one’s own culture and values, without depending on military and economic power.” In today’s international society, while hard power, such as military force, continues to play an important role, the importance of soft power has been increasing as a result of the spread of information and democratization, and the expansion of players other than governments.
