| After World War II,the United States has a deep-rooted interest in maintaining the dominance of the global maritime order.In the South China Sea,China’s maritime development strategy has increasingly aroused the insecurity of the United States,and the United States has been increasingly hostile to China’s maritime development.The South China Sea region has become one of the focuses of the prominent structural contradictions and strategic competition between China and the United States.As the COVID-19 epidemic accelerates the transformation of the world structure and the change of the international order,the order in the South China Sea has entered into a new round of adjustment since the end of the Cold War.The United States is increasingly anxious about the situation in the South China Sea,it’s popular domestic view is "China is controlling the South China Sea" and "The United States has not adopt an effective response yet." In this context,the South China Sea policy of the Biden administration has become one of the key areas of US foreign policy.The Biden administration’s South China Sea policy not only reflects the continuity of the US South China Sea policy,but also has new characteristics and trends,which will directly affect the development trend of the South China Sea and the future development of China-US relations.The formation and development of the U.S.South China Sea policy,the specific policy analysis of the Biden administration,and the impacts brought about by the policy constitute the main structure of this research.Since the Spanish-American War,the United States’ South China Sea policy has gone through historical stages of germination,growth,development,expansion and institutionalization.After Biden came into power,the new development concept of the US South China Sea policy and the changing domestic and foreign environment determined that its policy had a more negative regional and international influence.The Biden administration,on the basis of inheriting the Trump administration’s overall tough line on the South China Sea policy,has adopt a series of measures to strengthen its policy: focusing on shaping "competition as the mainstay + cooperation as the supplement",focusing on shaping the "containment + military deterrence" system,increasing the "rebalancing" of military power,and focusing on shaping ideology and American values--forming a set of containment and deterrence system against the rise of the China.This system is in the overall containment strategy system of the United States.It is the inheritance and development of the Obama administration’s "Asia-Pacific rebalancing" strategy and Trump’s "Indo-Pacific strategy",which is a specific and detailed version of the previous government’s South China Sea policy.It is more rational and in-depth than the previous government’s general strategy.The Biden administration’s South China Sea strategic system has built the South China Sea into a strategic platform for strategic competition between China and the United States,which will undoubtedly exacerbate the geopolitical and military information technology competition tensions in the South China Sea.Strategic competition has become increasingly in-depth,extensive and internationalized,which is seriously affecting the development process of world peace and security.At the same time,it should also be noted that the implementation of the Biden administration’s South China Sea policy system requires a specific environment as a premise,and the practical dilemmas it faces and the characteristics of the policy determine that the strategic system can only stay at the level of theoretical conception.Regarding the aggressive policy system,China will resolutely defend the country’s historical sovereignty,firmly oppose other countries’ meddling in South China Sea affairs,and expect the two sides to manage conflicts and differences,and actively guide the development of China-US strategic relations. |
