U.S. policy toward China has shifted from "engagement" (1970s-2010s) to "strategic competition" under both Trump and Biden administrations. Taiwan is the central flashpoint: the Taiwan Relations Act (1979) commits the U.S. to provide Taiwan defensive arms and to view any non-peaceful effort to determine Taiwan's future "of grave concern."
Key debates:
- Strategic ambiguity vs. clarity: Whether to declare unambiguously that the U.S. would defend Taiwan against PRC attack.
- Arms sales to Taiwan: Pace, mix, and political signaling.
- Defense posture: U.S. force structure, basing, and exercises in the Indo-Pacific.
- Economic decoupling: Tech export controls (advanced chips, EDA tools), investment screening, sanctions.
- Engagement: Whether to maintain working diplomatic and military channels.
