BEIJING — Output of raw coal in China fell 6.3 percent year-on-year to 490 million metric tons in the first two months of 2020 as the novel coronavirus outbreak disrupted production, official data showed.

During the January-February period, Chinese railways transported 370 million tons of coal, down 6.2 percent year-on-year, according to data from the National Bureau of Statistics.

As the spread of the virus has been basically curbed in China, a majority of coal miners have restored normal operation.

By the end of February, coal stockpiles at the country's major power plants were adequate for 27 days of consumption, the data showed.
