However, 2020 looks uncertain with economic activity stalling in many parts of China as it grapples to contain the virus that has killed more than 2,700 people and spread to over two dozen other countries. “Today, our iron ore books are full. But we are likely to see some short-term impact such as on supply chains and possibly in provisional services from Chinese suppliers,” Chief Executive Jean-Sébastien Jacques told reporters in a teleconference. —Reuters
