SEOUL, May 15 (Reuters) - Qatar Airways will soon announce an investment in an airline in southern Africa, its CEO said on Wednesday, part of the Gulf carrier's drive to expand its network in Africa.

"We are at the final stage of an equity investment in an airline in the southern part of Africa," Badr Mohammed Al Meer said on a panel at the Qatar Economic Forum in Doha, saying the deal could be announced in two to three weeks. (Reporting by Lisa Barrington;Editing by Elaine Hardcastle)
