The most-traded January iron-ore on China's Dalian Commodity Exchange ended daytime trade 2.1% higher at 728 yuan ($100.64) per metric ton.
On the Singapore Exchange, the benchmark September iron-ore jumped 2.2% to $103 a metric ton, as of 07:30 GMT, paring the previous day's losses.
"Scant mildly positive headlines have provided temporary relief from the overarching disappointment of a flailing economy. This only creates mouth-watering opportunities for iron ore bears to sell into and soak up additional speculative gains on short positions," said Atilla Widnell, managing director at Navigate Commodities in Singapore.
