With the discovery of several asymptomatic cases of COVID-19 in Shenzen, shipping firms are warning clients of shipment delays out of Yantian International Container Terminal (YICT), one of China’s busiest container ports. Tracking data on Thursday showed more than 40 container ships anchored in open water outside the terminal. Top international container lines said they would be skipping some port calls to Yantian to ease pressures and some vessels may be re-routed to other destinations.
