China's coal production fell 3.5 percent to 3.68 billion tonnes in 2015, with major miners slashing output as a result of waning demand, falling prices and a concerted effort by authorities to cut the country's dependence on fossil fuels.
The production of coking coal, used in steel, fell 10.4 percent annually in the first two months of the year to 66.5 million tonnes. It fell 6.5 percent in the whole of 2015.
