In 2017，Japan’s Liberal Democratic Party（LDP）has won the 48th Election of House of Representatives under the leadership of Shinzo Abe，taking a step towards Abe’s “extra long-term administration” and the transformation of national strategy driven by the security policy. The LDP proposes a theory of “the Self-Defense Force（SDF）into the Constitution” and implements the revision of Japan’s constitution. In terms of foreign affairs，the Abe administration attempts to promote the strategic coordination between Japan，U.S and EU，put the new security legislation into practice and incorporate the NATO into the Asia-Pacific security issues. It also seeks for a leading role in the “Trans-pacific Partnership（TPP）without U.S.” and the advancement of “Indo-Pacific Strategy”. Meanwhile，Japan has taken a more positive attitude towards China’s Belt and Road Initiatives（BRI）. There is a growing trend of recovery of Sino-Japanese relations，with sensitive and controversial issues remaining unsolved. The Abe administration insists on a double-track tactic in its policy towards China. The strategic competition between China and Japan has intensified，with the focus of rules and norms on multilateral and regional level and uncertainty for the improvement of Sino-Japanese relations.
