This month, G20 leaders will endorse guiding principles for “quality infrastructure investment”, a priority for Japan. China’s support of these principles signals a willingness to address criticism of its Belt and Road Initiative. China and Japan, rivals in delivering high-speed rail, appear open to collaborating on projects that would meet high sustainability standards, writes Motoko Aizawa, President of the Observatory for Sustainable Infrastructure, who for 12 years headed the Policy and Standards Unit in the Environmental and Social Department of the International Finance Corporation (IFC).
