Fuel shortages in Shenzhen brought chaos to the Huanggang border checkpoint yesterday, with a queue of container trucks several kilometres long all but bringing traffic in the area to a standstill. A Shenzhen government spokesman denied there was a fuel shortage, but truck drivers complained they could not fill up in Shenzhen or Dongguan. 'It has been like this for two weeks. But today it is particularly serious because it is a Friday and many container drivers returned to work after the May 1 holiday,' Cheung Man-shing, a container driver from Hong Kong, said. Another container driver said the service station at Huanggang was rationing drivers to 50 yuan worth of diesel. 'Some drivers have to queue up twice to fill up,' he said. Tse Long, vice-president of the Container Transportation Employees General Union, said long-distance drivers had encountered the same problem a month ago. Service station operators had been limiting drivers' purchases because the government would not let them raise prices in line with increases in wholesale fuel prices. 'The service stations have enough fuel for drivers. But they figured that they would rather keep the fuel than sell it at a loss,' said Mr Tse.
