Authorities are implementing new debt financing tools, including customized green bonds, designed to support the large-scale equipment renewal and consumer goods trade-in projects across China, Securities Daily has reported. Zhang Xinyuan, head of research at Co-Found Think Tank said the new tools can reduce financing costs, help enterprises update equipment, and provide more investment opportunities. China Construction Bank recently participated in underwriting four medium-term notes with a total issuance of CNY5.6 billion, which will be partly used by China Southern Power Grid on power grid improvement projects, the paper said.
