BEIJING, July 19 (Reuters) - Three-month zinc on the London
Metal Exchange (LME) gave up early gains to trade sharply lower
on Thursday as another broad sell-off in industrial metals took
hold.
    Shanghai zinc had earlier jumped by the daily limit of 6
percent to a one-week top following a report that China plans to
boost liquidity in the banking sector, and was underpinned by
falling inventories and a weaker yuan.
    The LME sell-off that followed came as a China foreign
ministry spokeswoman described as "shocking" comments from U.S.
economic adviser Larry Kudlow that Chinese President Xi Jinping
was "holding up" a deal to resolve a trade row between the two
countries.
    Matt France, head of Asia institutional metal sales at
brokerage Marex Spectron, said in a note that dips in metals
prices "continue to offer up value on an intra-day basis" but
"the bearish trend remains intact."
