US-China Relations
Structure and Key Fault Lines
The United States and China are the world's two largest economies and the defining bilateral relationship of the 21st century. Key structural tensions include: trade imbalances and tariff disputes (escalating since 2018); competition in semiconductor technology, artificial intelligence, and 5G; the Taiwan question; South China Sea territorial disputes; and differences over global governance institutions. Despite tensions, both sides maintain deep economic interdependence — bilateral trade exceeded USD 600 billion annually at its peak — and have established multiple communication channels to manage competition.
- US-China trade war formally began in 2018 with reciprocal tariff escalations; tariffs have remained a central point of dispute.
- Technology competition focuses on semiconductor chips, AI, quantum computing, and space — the US has imposed export controls on advanced chips and chip-making equipment.
- Summit-level US-China meetings are relatively rare; the last presidential visit to Beijing before 2026 was in 2017.
- The Iran conflict referenced in the summit agenda relates to a military confrontation involving Iran that delayed the originally scheduled summit.
