North–South development competition and the quality and sustainability of Chinese and Japanese trans‐national infrastructure initiatives

China has become a recent rising power in global development cooperation in the past few years. This paper examines how the Global North, as represented by Japan, responds to the rising of the Global South, as represented by China, in infrastructure support. This paper positions itself in the context of Global‐North/South and triangular cooperation to compare Japan's Partnership for Quality Infrastructure with China's Belt and Road Initiative from the dimensions of policy rhetoric, finance mechanism, environmental sustainability and rule of law. This paper draws the conclusion on whether the North–South competition enhances the quality and sustainability of those initiatives.
