Chinese authorities announced 31 October a rise in the prices of gasoline, diesel and aviation fuel by 500 yuan (67 dollars) per ton, or roughly 10 percent. The increase, effective the following day, came after fuel shortages swept petrol stations from southern China to Inner Mongolia in the far north as refiners cut supply because domestic prices lagged far behind record global crude prices.
