America's geopolitical cognition of “Indo-Pacific” has gone through a long period, while the issuance of Indo-Pacific Strategy by the Trump administration seems to be a little hasty, which results from, to a large degree, the joint efforts of American Establishment and allies such as Japan and Australia. From the perspective of strategic design, although the US issued the Indo-Pacific Strategy Report, the concept of India-Pacific Strategy has yet to be fully formed. It mainly reflects the demands of the US in this region and demonstrates a trend and direction. The core issue is that as the Indo-Pacific region becomes more important, the US hopes to maintain and expand its military, diplomatic, economic and cultural advantages in the region, with the aim to better curb China's rise at sea and increase of regional influence. In terms of progress and potential of America's Indo-Pacific Strategy, the developments of its main pillars of military, economic and cultural values are not balanced. The military strength of the US stands out, while progress in other areas is relatively slow. A comprehensive assessment shows that the Indo-Pacific strategy of the US still faces many challenges. In which, the biggest problem is the lack of feasible path and reliable resource support. There is a long way to go before the strategy witnesses a complete implementation. However, even if partially realized, the strategy would pose a serious threat to China's national security and surrounding  environment.
