Iron-ore, coking coal skid again in China as demand concerns emerge

Prices of steelmaking commodities iron ore and coking coal fell sharply on Thursday, pressured by worries over slower demand as Chinese mills curb output in line with Beijing's campaign to fight smog. Iron ore futures slid more than 4% and coking coal dropped more than 5%. Rebar steel futures tumbled over 4% as data showed China's steel output rose year-on-year in September, though below the monthly record reached in August.
