In 2025, the US military continued to strengthen its military deterrence against China, maintaining high-intensity operations including close-in reconnaissance, Taiwan Strait transits, forward presence, strategic cruising, military exercises and drills, as well as battlefield preparation in the South China Sea and its surrounding areas. Among them, large reconnaissance aircraft conducted about 1,200 missions, and ocean surveillance and oceanographic survey ships accumulated 197 ship days of activity. Carrier strike groups (CSGs) have entered the South China Sea 9 times, demonstrating a strong presence. At least 11 nuclear submarines appeared in the region throughout the year, signaling a clear deterrence intention. Furthermore, bombers conducted 13 sorties across 7 deployments into the South China Sea and its surrounding areas, frequently rehearsing “north-south converging maneuvers” and “distributed operations”.

In 2025, non-US extra-regional countries continued to expand their military presence in the Western Pacific, undertaking activities such as reconnaissance patrols, Taiwan Strait transits, forward deployments, drills and exercises, as well as port calls. The UK and France deployed carrier strike groups (CSGs) to the region, and conducted joint drills with allies like the US and Japan. Australia performed multiple declaratory operations in the name of defending “freedom of navigation” in the South China Sea and participated in multilateral maritime cooperation activities led by the Philippines. Additionally, countries such as Canada, New Zealand, and India actively took part in multinational patrols and exercises.

Over the past 70 years, China’s role and contributions in safeguarding maritime safety in the South China Sea have been widely recognized. Especially in the past decade, China has made steady and commensurate contributions through initiatives such as providing intelligent navigation services, strengthening maritime disaster prevention and mitigation, developing an integrated sea-air search and rescue system, and deepening international cooperation against transnational maritime crimes.

In 2024, the US military continued to strengthen its military deterrence against China, maintaining high-intensity operations including close-in reconnaissance, Taiwan Strait transits, forward presence, strategic cruising, military exercises and drills, as well as battlefield preparation in the South China Sea and its surrounding areas. Among them, large reconnaissance aircraft conducted about 1,000 missions, and ocean surveillance and measurement vessels accumulated 706 ship days of activity, marking a significant increase compared to 2023. Carrier strike groups (CSGs) have entered the South China Sea 8 times, demonstrating a strong presence. At least 11 nuclear attack submarines, two guided missile submarines and one ballistic missile submarine appeared in the region throughout the year, signaling a clear deterrence intention. Additionally, the number of batches and sorties of bombers entering the South China Sea has significantly increased, with frequent exercises of “north-south double” and “distributed operations”.

In recent years, driven by US attempts to “contain China” using maritime disputes, tensions in the South China Sea have escalated. The intensification of certain disputes has attracted significant international attention. However, current frictions mainly exist among some disputing parties, and any relevant disputes have not affected other countries’ navigation and overflight freedoms in the South China Sea. China-US militaries’ interactions and encounters in the area are generally professional and safe. The impact of great power competition on navigation and overflight freedoms in the South China Sea remains manageable. The primary threats to maritime navigation are non-traditional security factors such as geographical obstacles, natural disasters, unbalanced development, piracy, and armed robbery against ships, which have long been overlooked and lack due attention.

In 2023, the US military continued to strengthen its military deterrence against China, maintaining high-intensity activities including close-in reconnaissance operations, Taiwan Strait transits, forward presence, strategic cruising, military exercises and drills, and battlefield preparation in the South China Sea and its surrounding areas. Around 1,000 sorties of large reconnaissance aircraft conducted close-in reconnaissance, frequently approaching Chinese mainland airspace. Carrier strike groups (CSGs) and amphibious ready groups (ARGs) entered the South China Sea eight times, with increased duration, and training intensity. At least 11 nuclear attack submarines (SSNs) and two ballistic nuclear missile submarines (SSBNs) appeared in the region, signifying a clear intent for deterrence. Additionally, both joint operations with allies and partners and the use of unmanned systems were prominent among the US military activities in the South China Sea in 2023.
