METALS-Copper gives up gains, down on Chinese worries LONDON, Feb 5 (Reuters) - Copper prices dipped on Wednesday, resuming a downtrend after a brief bounce, as investors worried about weak demand in China and about the adjustment of the Chinese market to a drop in London prices when it reopens on Friday. Copper rebounded on Tuesday and early on Wednesday from two-month lows, but those gains faded as the session wore on. Three-month copper on the London Metal Exchange fell 0.2 percent to $7,028.25 a tonne by 1555 GMT, down from a session high of $7,085.
