Power supply slowly returning

PetroChina and Sinopec, the country's leading oil companies, have increased fuel supplies to earthquake-affected regions to assist disaster relief work, the firms said yesterday.

PetroChina, China's largest oil firm, announced a move to allocate 100,000 tons of refined oil to ensure supplies in the areas.

Some refineries have been ordered to increase production, the company said. Its Lanzhou refinery, for example, has increased production by 10 percent.
