Asian firms eye overlooked parts of Angola economy.

LUANDA, Jul (Reuters) - Chinese and other Asian firms are diversifying in Angola, seeking out investments in overlooked sectors of the oil-dependent southwestern African nation's economy, a senior Angolan official said on Friday.

China, which is expanding its trade links with Africa in a bid to find natural resources for its energy-hungry economy, has already invested several billion dollars in the Angola economy through an oil-backed credit loan.
