Abstract:Economic diplomacy is an important form of diplomacy in the era of globalization, but there is a lot of debate on this concept and generalization of it as well. To a large extent, a diplomatic theory is actually a summary of a country’s diplomatic practice. A vague concept and generalization leads to the decline of theoretical logic and explanatory power. We need to redefine “economic diplomacy” from its background and its use in international relations, and strictly limit its range in order to better integrate it into a country’s foreign policy. Economic diplomacy is the extension of diplomacy in economic field for nations to realize their economic interests. Its basic features are economic goal-oriented, peaceful and indecisive, of which the first feature is the most important. Economic diplomacy has long been used as diplomatic means, but it appeared as a new phenomenon as it is elevated to be national policy or strategy only when a country and international relations are in a certain stage of development.
