The Korea-China Free Trade Agreement finally arrived at its preliminary settlement, in the 14th round of negotiations, held on November 10, 2014. This FTA is expected to function as an essential stepping-stone for future trilateral trade agreement between China, Japan and Korea. Further, it is anticipated to considerably contribute to shaping an integrated economic community for East Asia. Therefore, it assigns a diplomatic task of reconciling the speed of growth and harmonizing different systems of the three countries; it is beyond the matter of simple market invasion. This short paper aims to track the process to the settlement of the Agreement and analyze its sectorial substances, from the viewpoint of strategic and diplomatic dynamics in East Asia. The author thereby attempts to suggest a direction of future discussion towards joint subjects of cooperation.
