BEIJING -- The Chinese government on Wednesday announced a cut of 20 percent in the fuel surcharge on domestic flights from later this week, days after a reduction in the wholesale price of aviation kerosene.

The National Development and Reform Commission (NDRC), the national economic planning agency, said the 100-yuan (12.9 US dollars) surcharge per air passenger on domestic flights of or beyond 800 km would be reduced to 80 yuan (10.3 US dollars) from Sunday.

The agency also said the 60-yuan (7.7 US dollars) surcharge per passenger on flights of less than 800 km would be cut to 50 yuan (6.4 US dollars).

In a joint circular issued by NDRC and the General Administration of Civil Aviation, the surcharge for children, police and soldiers injured on duty will drop from 30 to 20 yuan (2.6 US dollars) for short flights, and from 50 to 40 yuan or flights of or more than 800 kilometers.

"The government authorities at all levels should strengthen their supervision over the air carriers to ensure the enforcement of the surcharge cut and safeguard the interests of air passengers," said an official with the NDRC price bureau, who refused to give his name.

The government reduced the aviation kerosene wholesale price by 90 yuan (11.6 US dollars) per ton on January 14 as the international crude oil price had been declining since last September.

Crude oil prices fell to a 19-month low on Tuesday. New York's main oil futures contract, light sweet crude for delivery in February, fell 1.78 dollars to close at 51.21 dollars a barrel.

To counteract the huge rise in costs of the aviation industry brought by the high oil prices, China twice raised the fuel surcharge last year, almost tripling the surcharge it resumed on August 1, 2005.
