China Development Bank (CDB), the mainland’s largest policy lender, could raise its stake in mining firm Anglo American as the company’s share price falls, the South China Morning Post reported. CDB currently holds a small stake of less than 3%, though the exact amount is not known. London-traded shares of Anglo American, the world’s fourth-largest miner, have fallen 64.84% to £12.95 (US$22.44) from a 52-week high of £36.83 (US$63.81) in May. Global commodities prices have dropped on negative sentiment about the world economy. CDB has held a stake in Anglo American since 2006. Anglo American did not comment on whether CDB would increase its investment.
