(Adds Shanghai closing prices; updates London prices) BEIJING, April 4 (Reuters) - Base metals fell on Wednesday after the United States announced fresh tariffs on 1,300 Chinese products, including some metal products, escalating a trade row with China, which has vowed to respond. China, the world's top metals consumer, saw the services sector growth ease to a four-month low in March, according to the private Caixin/Markit services purchasing managers' index (PMI), while the country's central bank renewed a pledge to crack down on the unregulated shadow banking sector. There is a view that "the passage of this money into commodity markets for purely speculative purposes has or certainly will be stopped and the removal of this liquidity will more than likely increase volatility," Malcolm Freeman, CEO of Kingdom Futures, wrote in a note. The Shanghai Futures Exchange will be closed from the evening of Wednesday, April 4, for the tomb-sweeping holiday and will re-open on Monday, April 9.
* SHFE COPPER: The most-traded May copper contract on the Shanghai Futures Exchange closed down 0.2 percent at 50,280 yuan ($7,986.66) a tonne, after five straight sessions of gains, as brokerages trimmed positions before the four-day weekend.
