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

The rivalry between the United States and China is the dominant factor shaping political and strategic dynamics in the Asia-Pacific region in 2026, driving regional security priorities and economic governance. Both nations are intensifying competition over maritime routes, energy resources, and strategic areas including Taiwan, the South China Sea, and the Korean Peninsula, while China strengthens its military capabilities near Korea and in contested waters. The U.S. 2026 National Defence Strategy reinforces a shift toward deterrence by denial along the First Island Chain, explicitly framing China as the pacing challenge and downgrading other global priorities. This major power competition, combined with regional vulnerabilities and deep economic interdependencies, creates a dense and potentially unstable environment across the Asia-Pacific, though systemic escalation remains constrained by high costs.
