Hesai Technology, China's largest maker of lidar (optical radar) sensors, plans to build factories overseas next year as customers urge it to avoid geopolitical tensions. In an interview, Andrew Fan, chief financial officer of Hesai Technology, said the company is seeking to build production lines overseas in addition to its Chinese factories to "avoid geopolitical and tariff-related risks." "Customers who want to diversify their risks find this a wise approach," he said, adding that a diversified supply chain can also hedge against potential logistics disruptions.
