MANILA, June 9 (Reuters) - Copper futures jumped on Wednesday after Reuters reported that China's total exports surged in May, showing the economic strength of the world's top consumer of the metal.
Chinese exports grew about 50 percent in May from a year earlier, sources said ahead of the release of official data on Thursday, much bigger than market expectations and fueling a nearly 3 percent rise in Chinese stocks .SSEC. [ID:nTOE65805R]
The numbers breathed new life into equity and commodity markets that have been pummelled by worries over a spreading debt crisis in Europe.

"A lot of people are still pretty worried about the situation in Europe, whether it's going to be an even bigger problem than it is now," said Judy Zhu, commodity analyst at Standard Chartered Bank in Shanghai.
LME copper has lost more than 22 percent since hitting this year's high above $8,000 in April, pounded by Europe's credit crisis and fears of slower demand from China.
"Markets are still lacking any monumental news that could turn the bearish mindset around," said MF Global analyst Edward Meir.
