LONDON, July 13 (Reuters) - Aluminium rose nearly 3 percent on Thursday as concerns over potential supply curbs in number one producer China sparked a rally in the metal.
Talk that more capacity cuts were on the way in China fed into broader-based concerns over slowing output to push prices higher, analysts said. An industry association said last month that China will launch a crackdown to curb illegal expansion of aluminium capacity.
"This is all about the looming cutback to Chinese supply growth, due to both the current investigation into illegal capacity, and in the medium to longer term the expected slowdown in Chinese capacity growth," Julius Baer analyst Carsten Menke said. "Demand is not the issue -- it's all about supply."
