Professor Yee-Kuang HENG’s article titled “Japan in the Gulf: Between Washington and Tehran” was published in an academic journal, The International Spectator.


Whereas Japan’s hedging vis-à-vis China in the Indo-Pacific has predominantly been the focus of academic analysis, hedging also explains Tokyo’s policy choices in the Gulf to a significant degree. Yet, existing literature has largely overlooked Japan’s hedging behaviour in the Gulf, which had to navigate the uncertainties generated by two competing powers, the United States and Iran.
