The two Taiwan Strait crises took place during a particularly tense period of the Cold War. Although each incident was relatively brief, their consequences loom large. Based on analyses of newly available documents from Beijing, Taipei, and Washington, Pang Yang Huei challenges conventional wisdom that claims Sino-US misperceptions of each other’s strategic concerns were critical in the 1950s. He underscores the fact that Washington, Taipei, and Beijing were actually aware of one another’s strategic intentions during the crises. He also demonstrates conclusively that both “crises” can be understood as a transformation from tacit communication to tacit accommodation.
