BEIJING, March 13 (Reuters) - Shanghai aluminium prices fell more than 2 percent on Tuesday, slipping below the 14,000 yuan ($2,213) a tonne mark for the first time since late 2016, just two days before winter output restrictions on Chinese smelters are due to be lifted. China ordered smelters in 28 northern cities to cut aluminium output by at least 30 percent from mid-November to mid-March as part of an anti-pollution campaign. Argonaut Securities analyst Helen Lau said the March 15 restart had already been priced in, but new smelting capacity in China was adding even more supply to the market. "I'm sure a lot of these new smelters are keen to increase their production to full capacity as early as possible," Lau said, looking to recover their investment, even at low prices. The new plants may be able to break even below 14,000 yuan a tonne, she added. Many Chinese smelters are losing money at current price levels, industry sources say.
