East Asian countries are increasingly using artificial intelligence and drones to update their defense systems, driven by growing concerns over regional stability. Japan, South Korea, and Taiwan are all investing heavily in advanced military technologies, such as AI systems that assist in decision-making, affordable drones, and tools to combat psychological warfare and false information. Japan’s Ministry of Defense has asked for a record 8.9 trillion yen budget for 2027 to support these efforts, while South Korea has reached an all-time high of 53.9 billion dollars in defense spending, with military AI funding increasing by more than 100% to 264 million dollars. Taiwan has also approved a 7.6 billion dollar plan over five years to develop and purchase defense drones, aiming to create a force of 200,000 unmanned systems. China is also expanding its use of AI in military applications, incorporating it into areas like detection, intelligence gathering, targeting, command systems, simulations, planning, networking, and autonomous operations. The Chinese military, known as the People's Liberation Army (PLA), has made "intelligentization" a central goal in its modernization strategy, adding it to mechanization and informatization as key pillars. This shift has been influenced by the war in Ukraine, where the effectiveness of AI-powered drone swarms was observed, prompting the PLA to focus on developing large groups of autonomous drones to overwhelm enemy defenses. The United States is carefully watching the progress of AI and drone technology in this region, aiming to keep its technological edge over China. American defense strategies since December 2025 have highlighted the importance of AI as a core part of national security. However, the approaches of the United States and China differ in how they think strategically, with Western nations often using a methodical, step-by-step approach—like the game of chess—while China is said to think more holistically, akin to the game of Go. The quick development of these military technologies could make future conflicts more likely, as the lower cost of warfare might make it more tempting to start a war. A conflict involving Taiwan could lead to a 10.2% drop in global GDP, with major economic consequences, especially for the semiconductor industry. Taiwan produces over 90% of the world’s most advanced chips, and this economic impact might act as a deterrent against military escalation in the region.
