BEIJING, Jan 10 (Reuters) - London copper prices shrugged
off early losses to rise for a second session on Thursday, as a
weaker dollar enabled the metal to hold gains made from optimism
over the latest round of U.S.-China trade talks. 
    A weaker greenback makes dollar-denominated metals cheaper
for holders of other currencies and can support prices.
    However, prices in top consumer China failed to sustain the
momentum, with Shanghai copper slipping 0.1 percent. 
    Recent transactions in the refined and scrap copper markets
have been ordinary, consistent with the off-season, and
"fundamentals cannot support the copper price," Jinrui Futures
wrote in a note.
    Instead, prices for copper, an economic bellwether, will
move higher on improving macro sentiment and lower on weakening
sentiment, the Chinese brokerage added.
