MELBOURNE, March 15 (Reuters) - London aluminum hovered near its lowest since late December on Thursday on expectations of rising supply as China's winter pollution controls expire.
* ALUMINIUM: London Metal Exchange aluminum crept up 0.2 percent to $2,094 a tonne, having slipped to the weakest since Dec. 19 at $2,087 on Wednesday. Support is seen at the 200 moving day average at $2,083, a break of which could trigger a steeper correction, as it would send a sell signal to momentum following funds.
* SHFE: Shanghai aluminum hit its lowest in 14 months at 13,820 yuan ($2,191) on Tuesday and last traded at 13,950 yuan.
* SMOG: The winter heating season ended on Thursday. Aluminum smelters in 28 northern Chinese cities had been told to reduce output by at least 30 percent from Nov. 15 to March 15, although the actual volume cut was below expectations, putting pressure on prices.
* OUTPUT: China's aluminum production fell 1.8 percent in January-February from a year earlier, data showed on Wednesday, as the country's pollution crackdown and supply-side reform kicked in. An estimated 4.4 million tonnes of new capacity are expected to be completed this year
* STOCKS: Shfe aluminum <AL-STX-SGH> stockpiles held at exchange warehouses are within a whisker of record highs near 850,000 tonnes, reflecting a surplus of domestic material.
* DISCOUNT: The discount between cash Shfe and physical prices <AL-A00-CCNMM> has narrowed to 35 yuan from 385 three weeks ago, reflecting a tightening market and an expected pick-up in nearby demand.
* COPPER: LME copper traded up 0.3 percent at $7,006 a tonne by 0157 GMT, adding to 0.6 percent gains from the previous session. Prices are expected to rise over the coming month as industrial production in the seasonally strongest second quarter ramps up.
* TRADE: The Trump administration is pressing China to cut its trade surplus with the United States by $100 billion, a White House spokeswoman said on Wednesday.
* COBALT: Glencore, the world's biggest producer of cobalt, has agreed to sell around a third of its cobalt production over the next three years to Chinese battery recycler GEM.
* SMOG: Eastern China's Jiangsu province will step up its war on pollution and focus on "high-quality development" following a spike in smog early this year.
* DOLLAR: Supporting metals, the dollar fell against the yen on Thursday as lingering worries about global trade tensions weighed on investors' risk appetite.
