Taiwan Strait
Strategic Significance and Regional Security
The Taiwan Strait is an ~180 km wide waterway separating Taiwan from mainland China. It is one of the world's most strategically contested maritime zones, carrying approximately 50% of global container shipping traffic annually. China's People's Liberation Army (PLA) conducted unprecedented military exercises around Taiwan in August 2022, April 2023, and May 2024, simulating a blockade and rehearsing rapid seizure scenarios.
- China's position: Taiwan is a breakaway province; reunification — including by force if necessary — is non-negotiable
- Taiwan's position: de facto independent state (Republic of China) with its own military, democracy, and foreign relations
- US policy: "Strategic ambiguity" — the Taiwan Relations Act (1979) commits the US to provide Taiwan with defensive weapons but does not explicitly commit military intervention
- Japan's position: a Chinese military action against Taiwan would likely constitute "a threat to Japan's peace and security" (2021 Japan-US joint statement, first since 1969 to mention Taiwan)
- Yonaguni Island (Okinawa Prefecture): 110 km from Taiwan; population ~1,600; GSDF coast-watching unit established 2016; missile deployment by 2031 will make it a frontline deterrence node
- The Nansei Islands (Ryukyu chain), of which Yonaguni is the westernmost, stretch from Kyushu to near Taiwan — Japan is reinforcing military presence across all these islands
