Shanghai copper futures rose by their 5 percent daily limit on Tuesday, boosted by expectations of a strong recovery in Chinas economy, a day after a nearly similar rise in London on falling inventories. The most-active Shanghai June copper contract rose to 30,830 yuan ($4,510) a tonne by 0555 GMT, 5 percent higher than its settlement price on Monday and marking its highest since early November.
The metal then retreated to 30,440 yuan at the daily close while London Metal Exchange copper for three-month delivery dropped $15 to $3,815 a tonne as of 0700 GMT.
