Abstract: While much has been written about US–China strategic rivalry, no study to the authors’ knowledge has conducted an empirical analysis of this rivalry. This article fills this gap by investigating whether and how this rivalry affects a country’s response to the Asian Infrastructure Investment Bank (AIIB). The findings of this article indicate that certain aspects of bilateral strategic ties indeed have strong effects on a country’s reaction to the Chinese bank. More specifically, shorter distance to higher a level of partnership with, and more arms purchase from Beijing lead to faster accession to the AIIB, while the shorter distance to Washington results in slower accession, controlling for other factors. In addition, economically developed countries appear to be consistently more eager to join the Beijing-led bank than economically underdeveloped countries. Full text available here.
