US–China Relations: Diplomacy, Conflict, and Strategic Competition (1949–2026)

Introduction

The relationship between the United States and China is one of the most important geopolitical relationships in the 21st century. The two countries are the world's largest economies, major military powers, and influential diplomatic actors. Their interactions shape global trade, technology, security, climate policy, and international institutions.

Although the United States and China cooperate in some areas, they are also strategic competitors. Their rivalry spans economics, technology, military power, cybersecurity, and regional influence.
