The 14,000-yuan mark is considered an average break-even for Chinese aluminium smelters, whose margins had been squeezed by a protracted price slump over 2018.
Analysts said aluminium was rising due to a brighter macro picture in China, the world's top metals consumer, which posted a better-than-expected 6.4 percent year-on-year growth in GDP in the first quarter, as well as improving demand in the peak second-quarter consumption season.
ICBC said recent data had reinforced its view that "green shoots" were emerging for China's industrial metals demand.
China's fixed asset investment was up 4 percent month-on-month after seasonal adjustment, the bank said in a note, which "should be a material contributor to marginal industrial metals demand over the coming quarter."
