[Photo/Xinhua] China's latest index of export container transport hit a record high, reflecting a supply shortage of containers, mainly due to the nation's fast-growing exports. Tracking spot and contractual freight rates from Chinese container ports for 12 shipping routes across the globe, the average China Containerized Freight Index (CCFI) stood at 1,411.98 in the week ending last Friday, up by 6.7 percent from a week earlier, the Shanghai Shipping Exchange said. The CCFI rose nearly 70 percent since late May this year, roughly the same period when major Chinese ports saw a turnaround of container throughput.
