Strategic Ambiguity or Strategic Clarity: China’s Rise and US Policy Towards the Taiwan Issue

Observers have noted that Washington’s policy of ‘strategic ambiguity’ aims not only to deter China from attacking Taiwan but also to keep Taipei from taking actions that may be deemed provocative by Beijing leaders. Remarks and actions taken by former United States President Joseph Biden seem to place America’s long-held ambiguous policy in doubt. It has been argued that a clear security commitment from Washington is likely to bolster Taiwan citizens’ unrealistic expectations of America’s defence support and their calls for independence, which will certainly invite Beijing’s violent responses. Employing the theory of deterrence and survey data collected in Taiwan during the past 20 years, this article examines this argument. The analysis shows that the policy of strategy ambiguity remains crucial for the peace and stability across the Taiwan Strait. As China has increasingly turned itself to become a revisionist, Washington’s policy requires a recalibration, and the adjustment does not have to be a binary choice between ambiguity and clarity. Donald Trump’s return to the White House with his transactional approach to international affairs makes US policy towards the Taiwan issue less predictable, potentially leading to a volatile Taiwan Strait during his second term.
