The meeting of Sino-Japanese leaders in APEC summit in November is regarded as a landmark event of Sino-Japanese relations in the whole year of 2014. The meeting is based on the agreement of the four fundamental principles concerning the bilateral relations，and the consensus and meeting is the result of impact of various internal and external factors，as well as the interaction and gaming of both sides. The meeting contributes to relax the tension of Sino-Japanese relations，however，its aftermath effect and trend should be cautiously observed. In the context of the reform of Japanese defense and security policy，the upgrading of Japanese-U.S. alliance and the advancement of Japanese strategic diplomacy，there is a long-term trend of the lack of mutual trust and intensified strategic gaming between China and Japan. In 2015，there will be both positive and negative factors for the development of Sino-Japanese relations，with the outlook far from being optimistic concerning the improvement of Sino-Japanese relations through crisis management，dealing with historical issues properly，rebuilding strategic mutual trust and favorable sentiment between peoples.
