Port handles 60 mln tonnes/year of foreign and domestic seaborne coal. Guangzhou port, the largest coal transport hub in southern China, has halted foreign coal imports, according to traders who use the port and said they had been informed of the shutdown by customs authorities and senior company officials. Traders said the move caught merchants using Guangzhou by surprise and interpreted it as a sign of Beijing stepping up its campaign to cut pollution caused by the burning of coal. China already banned coal imports at small ports in July but Guangzhou has 14 coal berths and can handle 60 million tonnes of shipments per year. Chinese coal imports in the first seven months of 2017 totalled 110 million tonnes, an average of over 15.7 million tonnes a month.
