SINGAPORE - China steel futures fell more than 4 percent on Tuesday to hit their lowest since March as investors dumped riskier assets in a global rout triggered by fears political leaders are failing to tackle debt crises in the United States and Europe, Reuters reported.

The most active January rebar contract on the Shanghai Futures Exchange SRBc6 fell as low as 4,558 yuan per ton, its weakest since March 24. By 0132 GMT, it stood at 4,665 yuan, down 2.5 percent.
