From War on the Rocks:

Russia’s invasion of Ukraine has taught Taiwan many lessons about preparing for a possible Chinese invasion. Japan should also take this opportunity to learn. What more can Japan’s Self-Defense Forces do to prepare given their inevitable participation in any potential conflict over Taiwan?

Based on the Chinese Communist Party’s unwavering resolve to annex Taiwan, the People’s Liberation Army (PLA) has been developing air and naval forces as the major element of anti-access/area denial capability. Now, PLA air and naval assets can reach beyond the first island chain into the Western Pacific.
