BEIJING, Jan 28 (Reuters) - London aluminium prices fell on Monday after the United States formally lifted sanctions on Russian aluminium producer United Company Rusal. The sanctions had sent London aluminium to a seven-year high when they were announced in April last year amid fears of a supply squeeze, but prices had since fallen back on expectations that the measures would be withdrawn. There is likely to be little support from top aluminium consumer China in the near term, with the country shutting down for the week-long Lunar New Year break early next month. "This week end-user companies in eastern China have begun to suspend production for the holiday and demand has turned weaker," Jinrui Futures wrote in a note. Anticipated restarts to alumina production, including at Norsk Hydro's Alunorte plant in Brazil, could keep pressure on prices, it added. FUNDAMENTALS * ALUMINIUM: Three-month aluminium on the London Metal Exchange dropped as much as 1.4 percent to $1,892.50 a tonne shortly after the open and stood at $1,902.50 as of 0440 GMT. The most traded March aluminium contract on the Shanghai Futures Exchange was flat at 13,530 yuan ($2,010.73) a tonne. * RUSAL: Shares in Rusal, which said Jean-Pierre Thomas had resigned as chairman to comply with an imperative request from the U.S. Treasury, rose by more than 5 percent in Hong Kong after the U.S. announcement. * CHINA PROFITS: Earnings at China's industrial firms shrank for a second straight month in December on slowing prices and sluggish factory activity, piling more pressure on an economy in the grips of its slowest growth in nearly three decades. * TRADE: Chinese Vice Premier Liu He will visit the United States on Thursday and Friday for the next round of trade negotiations with Washington. * OTHER METALS: LME copper edged down 0.1 percent to $6.051.50 a tonne, while ShFE copper, tracking a jump in London copper on Friday, hit a one-week high of 49,750 yuan a tonne. Zinc was up 0.3 percent but all other LME metals were trading lower.
