Japan’s Taiwan Policy in the Xi Jinping Era: Moving Toward Strategic Clarity

Like the United States, Japan views its relations with Taiwan through a greater China framework. It uses a similar strategic ambiguity toward Taiwan to navigate its relations with China and Taiwan. However, Japan’s recent strong support for Taiwan to counter China’s pressure on the island seems to suggest that Japan’s Taiwan policy is moving away from its old strategic ambiguity toward a new strategic clarity. Why has Japan started to protect Taiwan proactively and directly in recent years? How to explain the transformation of Japan’s policy regarding Taiwan from strategic ambiguity to strategic clarity? Drawing upon various primary materials, this article approached those questions from a social constructivism lens. It argues that Japan’s new identity is a critical factor in Japan’s strategic transformation of its Taiwan policy. Japan’s new identity has first taken shape due to the growing challenge from China, and second been accelerated and hardened by the caprices of the United States. It is this new identity and its associated normative expectations that have caused Japan’s foreign behaviour to change fundamentally. This article will detail the process in which how Japan steadily changed its state identity over the years after showing that the existing explanations are unable to properly account for the shift of Japan’s policy toward Taiwan. Some policy implications will be offered in the conclusion section.
