Summary
Japan’s National Institute for Defense Studies, a think tank under the Ministry of Defense, published its China Security Report 2027 on November 13 and said the People’s Liberation Army is improving its ability to operate farther from China’s coast while placing high strategic value on control of the South China Sea. The report says that, amid intensifying US-China strategic competition, Beijing wants to use that control to deter or prevent US military intervention if it ever uses force against Taiwan. It argues that the South China Sea has become a key strategic base for countering US forces and for projecting Chinese military power into the Pacific. The report also urges Japan to expand security cooperation with ASEAN states and with US partners including Australia, Britain, and Canada.
Key Points
- The November 13 report, titled China Security Report 2027, was issued by Japan’s National Institute for Defense Studies under the Ministry of Defense.
- It says China’s navy is strengthening “far seas” or long-range operations to project force well beyond waters close to the mainland.
- The analysis says control of the South China Sea would help Beijing deter or block US intervention in a future military move against Taiwan.
- If the PLA could seal the Bashi Channel and secure air and sea superiority south of Taiwan, it could attack southern Taiwan from the South China Sea.
- The report says China is also using coast guard vessels and maritime militia in “grey-zone” activity to expand practical control without crossing into open conflict.
Why It Matters
For Hong Kong readers, the report points to a security environment in nearby waters that is becoming more contested, with the South China Sea and approaches to Taiwan treated as linked theatres rather than separate flashpoints. It also underlines why Japan is seeking tighter defence ties with ASEAN and other US-aligned partners, a shift that could further shape regional diplomacy and maritime security debates affecting Asia’s trade routes.
