BEIJING, June 29 (Reuters) - China's coking coal futures soared 8 percent on Thursday and were on track for their biggest one-day jump in seven months, boosted by a report the world's top consumer plans to ban imports into small ports, stirring worries about tightening supply.

Coke on the Dalian Commodity Exchange rose more than 5 percent to its strongest in three months, with its intraday peak at 1,773.5 yuan.
"The price rallies on coking coal and coke are driven by the worries about a supply shortage in the future, which helps lift the whole bulk commodities market," said Xu Bo, analyst at Haitong Futures.
