“Baosteel has been actively promoting yuan settlement in cross-border trading. The significance also lies in cooperating with leading upstream companies to explore the application of digital innovation such as blockchain in the traditional industry of raw material trading. It helps to improve the transaction flow and efficiency, and is a solid step forward on the path of the industry’s green development,” Baosteel’s head of raw material procurement said.
