LONDON, June 8 (Reuters) - Copper posted its biggest one-day rise since early April on Thursday as better than expected Chinese economic data allayed some concerns about oversupply, prompting a bigger bounce off this week's near three-week low.
China reported stronger than expected exports and imports for May despite falling commodity prices, suggesting the economy is holding up better than feared. China's unwrought copper arrivals also jumped month on month.
However, the metal remains vulnerable to further losses after pulling back 8 percent from mid-February highs, analysts said, on the prospect of slackening growth in China and tightening U.S. monetary policy.
"The market will grab any good news it can get, but the overall picture here is that we are looking at a softer Chinese economy, and in general a global economy that will not push ahead with the pace we saw in the first quarter," said Danske Bank analyst Jens Pedersen.
"That gives limited upside to copper."
