MELBOURNE, Feb 12 (Reuters) - London copper climbed away from its lowest in nearly two months on Monday as the dollar dropped, although traders remained cautious about demand after the Lunar New Year holiday that starts this week. Chinese demand for metals and supply constraints should be supportive in 2018, while recent price strength looks to be a function of global growth and demand, said Citi in a report. "(However) while we expect housing-related metals demand to stay fairly robust, potential slowdown of power infrastructure and machinery spending appears worrisome," it said. FUNDAMENTALS: * LME COPPER: London Metal Exchange copper rose 1.7 percent to $6,867 a tonne by 0346 GMT, recouping losses from the previous session when it lost 1.3 percent to hit $6,733 a tonne, the weakest since Dec. 14. Prices also crashed through the 100-day moving average, worsening copper's chart picture. * SHFE COPPER: Shanghai Futures Exchange copper cut losses to 0.3 percent at 51,660 yuan ($8,199) a tonne, having hit its weakest since late September amid a rout in China's sharemarkets ahead of the Lunar New Year. Open interest is at the highest in nearly two years. * HOLIDAYS: The Shanghai Futures Exchange will close from the evening of Feb. 14, 2018. * DEMAND: U.S. President Donald Trump will roll out an infrastructure plan on Monday that already faces significant hurdles in Congress because it does not offer as much new federal funding as Democrats want or directly address how to pay for the effort. * U.S. ECONOMY: A surprise surge in U.S. wage growth has rocked global stock and bond markets in the past week, and inflation figures from three of the world's biggest economies could dictate whether investors are in for another rollercoaster ride in the coming week. * POLLUTION: China's top steelmaking city of Tangshan said on Friday it would extend restrictions on production beyond the end of the winter heating season on March 15. * INVESTORS: Hedge funds and money managers cut their net long position in COMEX copper in the week to Feb. 6, U.S. Commodity Futures Trading Commission data showed on Friday.
