Introduced by the late Prime Minister Shinzo Abe and inherited and developed by Fumio Kishida,Japan's"Indo-Pacific"strategy has gradually taken shape.This strategy can be deemed a broad vision,covering a wide range of topics and an extensive network of partners,with a strong trend of pan-securitization.It is a comprehensive international strategy based on Japan's alliance policy and China containment strategy,following a global,security-oriented approach.Driven by considerations such as maintaining its economic status,realizing its long-cherished dream of becoming a political powerhouse,and containing China,Japan has stepped up its"Indo-Pacific"strategy,which may influence global development,undermine regional maritime security,and impede China's reunification process.Meanwhile,Japan's"Indo-Pacific"strategy faces the triple challenge of a strategic overdraft,the unstable economic foundations,and the weak external support.These constraints may not suffice to reverse the direction of Japan's"Indo-Pacific"strategy in the short term but will limit its effectiveness.
