US-CHINA RIVALRY DRIVES ASIA-PACIFIC GEOPOLITICS AND SECURITY IN 2026

The United States and China are intensifying competition in the Asia-Pacific region, focusing on maritime control, energy security, and militarization of strategic island groups like the Senkaku and Spratlys. This rivalry defines regional security priorities and economic governance, with Taiwan remaining a critical flashpoint due to its technological centrality. China is strengthening military capabilities near Korea and the South China Sea while conducting exercises, while Japan and South Korea consolidate their alliances with Washington. Strategic heterogeneity creates security risks, particularly in the China Sea and Southeast Asia, as major power competition and regional vulnerabilities drive geopolitical instability.
