Prime Minister Abe has reoriented Japanese diplomacy back to U.S.-Japan centric approach since his return to power in 2012. Abe has also tried to turn the problematic relations with China into the opportunity of reforming defense in order to regain Japan's strategic activeness. Abe diplomacy is following two main principles: the domestic affairs and easier diplomatic issues first, in order to carry out four strategies: The first is the defense reform and U.S.-Japan alliance reinforcement. The second is compromising of TPP, U.S. base and Marine Corps relocation in exchange for the U.S. understanding that Japan will not improve its relations with China in short time. The third is applying the bird's eye view of global affairs to bring Japan back to the world diplomatic stage and formulate favorable international environment and more bargaining chips for Japan to deal with China and South Korea latter. And the last is to utilize economic and trade issues to gradually improve Japan's relations to China and South Korea.
