What are the characteristics of China's maritime security geostrategic environment?

China's marine geo-strategic environment is characterized by complexity, multilateralism and crisis opportunity.

Geographical situation of China offshore. In the Yellow Sea, there is no serious demarcation dispute between China and neighboring countries, but the instability of the Korean Peninsula and frequent maritime conflicts between the two countries make China a security factor that cannot be ignored. Further south, in the East China Sea, in addition to the issue of Taiwan Province Province, there are also the Diaoyu Islands issue and the delimitation of the continental shelf in the East China Sea between China and Japan. So far, China and Japan have not reached a concrete and feasible solution. Although the problem of Taiwan Province Province is an internal problem of China, the hidden big country factor often complicates the problem. Therefore, solving the problem of cross-strait reunification is not only a matter between the mainland and Taiwan Province Province, but also needs to deal with the related big country factors. With the global shortage of oil and gas resources, the strategic position of the South China Sea in China is more prominent. Southeast Asian countries used their geographical advantages to occupy most of the islands in the South China Sea.

Geographical situation of China offshore. The United States is the first consideration. In the Pacific Ocean, the United States has built three island chains, which has become a major obstacle for China to go deep into the ocean. As early as the Cold War, the United States built an island chain strategy to contain Asian socialist countries and limit their strategic space. After the disintegration of the Soviet Union, the United States paid more attention to the strategic significance of the Asia-Pacific region, and one of its main purposes was to contain China with island chains. The island chain not only has political and military connotations, but also blocks the maritime transport lines, which is used to control the exchange of materials in China's international trade, especially the control of the oil lifeline, such as an invisible noose, which locks the waters of China, thus achieving the purpose of restricting China's economic development and security.
