Executive Summary

Taiwan is significantly boosting its defense capabilities with a supplementary budget for unmanned systems and the deployment of new long-range cruise missiles capable of striking mainland China. Concurrently, China is escalating its maritime presence east of Taiwan and engaging in economic coercion against Japan, while also conducting military exercises near the Philippines and diplomatic pressure in the Pacific.

Why It Matters

This document provides a critical snapshot of escalating military and diplomatic tensions in the Indo-Pacific, highlighting Taiwan's accelerated defense modernization, China's assertive regional expansion, and the complex interplay of economic and security strategies among key actors.

Key Takeaways

  • Taiwan is investing heavily in domestic defense, particularly unmanned systems and long-range cruise missiles, to enhance deterrence against PRC aggression.
  • China is normalizing a permanent maritime presence east of Taiwan and increasing military activities in the South China Sea, asserting territorial claims and projecting power.
  • China is employing economic coercion against Japan and diplomatic pressure in the Pacific to undermine Taiwan's international standing and expand its own influence.

Strategic Relevance

The report details Taiwan's efforts to develop asymmetric capabilities and retaliatory strike options, which could significantly alter the deterrence calculus in a cross-Strait conflict. It also underscores China's multi-faceted strategy of military modernization, gray-zone operations, and economic/diplomatic pressure to achieve its regional objectives, impacting regional stability and US alliance structures.
