The emerging US approach: "Spreading the Theater" is the continuous "Rebalancing" strategy in the Pacific. The purpose of this art is to congregate the US traditional allied relationships, develop further partnerships with friendly countries, maintain the US leadership and contain China's influence in the Asia-Pacific region. From the logic of power balance, the competition and cooperation between the US and China will continue to happen in various fields. The above conflicting phenomenon is a low-intensity and struggle-without- breakup pattern. In order to maintain our national security and development, we have to carefully consider the interest and relationship among all stakeholders in the US-China competition, modestly apply necessary and contingent measures and positively earn all supports.
