Japan’s Defence White Paper Ties Drone Development to Economic Growth Amid China-Centric Security Concerns

Tokyo’s annual defence white paper, adopted by the Cabinet on Tuesday, frames the nation’s accelerating military buildup as both a security imperative and a catalyst for broader prosperity. The 598-page (some reports describe it as 610-page) document identifies China as Japan’s “greatest strategic challenge” and highlights the expanding presence of Chinese warships in the Pacific and recent incidents in which Chinese aircraft locked radars onto Japanese planes during carrier drills near southwestern Japan. It also flags Russia’s joint operations with China and North Korea’s missile advances as “grave national security concerns.”
