Alf Barrios, chief executive Rio Tinto Aluminium, in an interview with Bloomberg, said that in the next 2-3 years, aluminum reserves would drop sharply, and advised the producers of this metal to create additional capacities outside of China. According to him, the growth in demand for aluminum is increasing, and there is no reason to hope for the growth of its exports to the PRC. According to the London Metal Exchange, aluminum stocks in September have fallen to their lowest level since 2007. Their decrease is observed two quarters in a row. Barrios said that Rio Tinto had already begun to expand its smelting capacity in Quebec.
