China iron ore dropped for a fourth straight session and coking coal hit a four-month low on Wednesday on prospects of weaker demand and easing supply concerns for the steelmaking materials in the world's biggest steel producer.
The most-traded iron ore for January delivery on China's Dalian Commodity Exchange was down 0.2per cent at 543 yuan (US$85.00) a tonne by 0330 GMT.
On the Singapore Exchange, iron ore's front-month December contract slipped 0.5per cent to US$88.65 a tonne after a 1.2per cent gain in the previous session.
A modest weekly decline of 1.5 million tonnes in iron ore arrivals at Chinese ports should provide temporary support to prices, Atilla Widnell, managing director at Singapore-based Navigate Commodities, said in a note.
