In peacetime, the conduct of highly-intensified military activities in another coastal state’s surrounding waters, such as thousands of close-in reconnaissance operations and hundreds of military exercises, is a clear violation of the spirit “maintaining international peace and security” of the UN Charter and "the peaceful uses of the seas" of the United Nations Convention of the Law of the Sea.
Since 2009, US military activities against China have strengthened in terms of the frequency and intensity. In 2021, there was a sharp rise in the US armed forces’ operations in the South China Sea compared with that in 2020, which poses increasingly high risks of China-US friction and conflict in the air and at sea.
In 2021, the US military strategy and operation on the South China Sea is featured by deterrence----strengthening forward military presence and targeted activities, to deter the imaginary “China might overreach”. However, over-deterrence will stimulate China’s decisive countermeasure, thus inevitably be backfired. In the future, deterrence and counter-deterrence, provocation and counter-provocation will be most critical strategies and tactics of US-China maritime interaction.
US military’s presence and operations in the South China Sea are the major factor affecting South China Sea situations. Since 2019, South China Sea Strategic Situation Probing Initiative (SCSPI) has released a yearly report An Incomplete Report on US Military Activities in the South China Sea. The report is intended for promoting the transparency of South China Sea Situations and providing the perspective of a third-party think tank for reference to government departments, research institutions, media and the public of related parties.
In 2021, the US placed great emphasis on military deterrence against China, and maintained highly-intensified military activities in the South China Sea, such as close-in reconnaissance, forward presence, “freedom of navigation operations (FONOPs)”, military exercises and drills, and battlefield preparation.
In 2021, the US warships and aircraft’s frequent transits through the Taiwan Strait and US officials’ visits to Taiwan released dangerous signals to separatists in Taiwan and extremely threatened the peace and stability of the Taiwan Strait.
In 2021, the U.S. strategic vision is shifting from strategic competition to integrated deterrence, with a combat concept focused on operational and actual combats with concepts of operations (CONOPS), and seeking to create a new generational gap with China in military equipment and technology.
In 2021, the US made greater efforts to pull extra-regional countries to involve militarily in the South China Sea, as China-US competition intensifies.

With a view to maintaining and promoting the peace, stability and prosperity of the South China Sea, we launched the South China Sea Strategic Situation Probing Initiative (SCSPI) in April of 2019. The Initiative aims to integrate intellectual resources and open source information worldwide and keep track of important actions and major policy changes of key stakeholders and other parties involved. It will provide professional data services and analysis reports to parties concerned, helping them keep competition under control, and with a view to seek partnerships.
