Powerful states often use tools of economic statecraft, such as foreign aid and other
financial policy instruments, in a bid to “purchase” influence as well as establish
regional leadership among their neighbors. How and why do these states undertake
similar economic statecraft strategies and policies? The article examines the evolution
of infrastructure financing policy of China and Japan and identifies the ever changing
and, yet at the same time, mirroring interaction between the two countries’ development
finance practices. We argue that emulation and competition have led to the
process of policy diffusion between these two countries. The competition between
these two foreign aid leaders in East Asia especially after China’s Belt and Road Initiative
has shaped the region’s infrastructure development dynamics as they strive
to move the equilibrium outcome to their advantage. Such equilibrium through the
policy diffusion process has important implications on global development governance.
