BEIJING, July 6 (Reuters) - London copper fell for a fifth
straight session on Friday and hit a fresh 11-month low as U.S.
tariffs on Chinese goods kicked in, escalating the trade spat
between the world's top two economies.
    Copper, seen as a bellwether for economic health, is down
5.5 percent in London this week, putting it on track for its
steepest weekly drop since the week ended Jan. 16, 2015.
    The United States imposed tariffs on $34 billion of Chinese
imports at 0401 GMT. Beijing has promised to retaliate in kind. 
    The U.S.-China trade dispute "looks like becoming
entrenched" and "comes at a time when copper demand suffers its
seasonal slowdown," ANZ wrote in a note. 
    "However, we feel the market is oversold. Supply disruptions
remain a threat, and shifts in China's consumption patterns will
see demand for refined copper remain strong," it said. 
    "If trade tension subsides, we would expect copper prices to
recovery strongly" in the second half of 2018, ANZ said.
