The global civilization view of the Communist Party of China in the new era internalizes the general requirements of civilization development based on its internal and external contexts, and also integrates the Chinese discourse of inclusiveness and global vision, realizing the transcendence of the Western civilization view. It follows the ontological logic of the dialectical unity of the general commonality and national identity of human civilization, and adheres to the theoretical logic of combining Marxism with the fine traditional culture. It is the historical consciousness of the Communist Party of China remaining the global vision, and also a realistic response to the influence of the highlighting of civilization values and the intensification of clash of civilization. It takes building a Human Community with a Shared Future as its overall goal, practicing the Humanitys Common Values as its common guideline, respecting the diversity of civilizations as its basic principle, valuing the inheritance and innovation of civilization as its important driving force, and strengthening international cultural exchanges and cooperation as its practical path. It highlights the strong sense of responsibility of the Communist Party of China in promoting the progress in human civilization, and has great significance in promoting theoretical innovation in international relations, promoting world peace and development, strengthening global civilization governance, and building a human community with a shared future.

With the rapid development of deepsea technology and equipment, the intensification of deepsea resource competition, the lag of deepsea military control mechanisms, and the need for comprehensive management of the ocean and potential sea battles, major military powers are accelerating the construction of deepsea combat systems, attempting to turn most of the deepsea areas from a public domain state into a new onedimensional battlefield, in order to seek control over deepsea areas, which will accelerate the development of militarization in the global deepsea region. The acceleration of militarization in global deepsea region will in turn promote a leap in deepsea technology, thereby driving the improvement of national ocean military strength and comprehensive national strength, and expanding the space for national development. At the same time, this acceleration will intensify the deepsea arms race, violating the basic principles and spirit of international ocean peaceful utilization, and greatly increasing the risk of major powers’ war. However, due to the significant investment in the development of deepsea militarization, the potential risks from widespread application of artificial intelligence technology and the harsh geographical and fragile ecological environment of the deepsea will also pose constraints and challenges to the accelerated development of deepsea militarization.

As critical infrastructure, undersea cables are becoming the focus of great powers and a new perspective to analyse the U.S. strategic approach towards China. Undersea cables have existed throughout the history of great power rivalry, during which the U.S. has repeatedly used it to attack its opponents. Undersea cables expand the dimension of great power infrastructure rivalry and has the developmentsecuritytechnologyspace nexus. Undersea cables have higher technical requirements and are the key to the Fourth Technological Revolution. Having been located in deep sea, undersea cables lack effective supervision and are more vulnerable to risks. The U.S. rivalry with China on undersea cables is mainly based on national security considerations. At the same time, it hopes to use undersea cables to suppress Chinese companies and reduce their market share, as well as maintaining technological dominance and deep sea hegemony. The U.S. competitive measures include forcing undersea cables to suspend construction or bypass China, cooperating with allies and partners to exclude Chinese companies from undersea cable market, restricting the export of undersea cable technology to China, and developing offensive undersea capabilities to attack China’s undersea cables. The rivalry between the U.S. and China on undersea cables will lead to a dual structure in the digital field and increase the difficulty of global digital governance. Besides, the rivalry will be detrimental to the improvement of connectivity in IndoPacific states and the growth of local enterprises. It will also weaken the strategic stability between the U.S. and China, which increasing the risk of accidental occurring in deep sea.
