China's aluminium market faces increased supply in second half
More capacity expected to come on stream in the second half as consumption stays steady

The oversupply of aluminium on the mainland is expected to escalate in the second half of the year as more new capacity is set to come on stream, further reducing the need for imports by the world's top consumer and producer of the metal.
Smelter sources said the stronger-than-expected consumption experienced in the first half would be maintained, but they did not expect further growth this year.
Imports dropped 67 per cent in the first half from a year earlier, official data showed.
Mounting supplies would also weigh on domestic prices, which have fallen more than 5 per cent so far this year, said Zhang Chenguang, an analyst at data provider SMM.
Beijing has tried unsuccessfully to limit aluminium capacity and further tightened regulations last month for new and existing smelters.
Analysts and smelter sources said the regulations would not cut production this year but would limit expansion in the longer term.
The mainland has more than 27 million tonnes of annual capacity. About 10 million tonnes of capacity was being built, the Ministry of Industry and Information Technology said on its website.
