Aluminum Corp of China (Chalco) has ended an agreement to buy a 29.9 percent
stake in Winsway Coking Coal as it would not be able to win approvals from
Chinese and overseas authorities by the September 30 deadline, it said in a
stock exchange filing late on Friday.

The move comes weeks after Chalco abandoned
plans to buy a majority stake in Canada”s Mongolia-focused coal miner South
Gobi Resources due to political hurdles.

Chalco had said in April that it would buy a
stake in Winsway, which supplies Mongolian coking coal imported into China, for
$308 million.
