In a statement to Reuters, Mobile World said it would announce the information once the deal was concluded.
The sources said the deal could value Bach Hoa Xanh, Vietnam's third largest grocery chain, at around $1.5-$1.7 billion.
Founded in 2015, Bach Hoa Xanh, backed by Vietnam's retail giant Mobile World Investment (MWG.HM), is running more than 1,700 stores in Vietnam's southern and south-central provinces.
The Ho Chi Minh City-headquartered company had first planned the sale of a stake of up to 20% in Bach Hoa Xanh last year.
Bach Hoa Xanh was expected to be profitable from next year, its managing director told investors last month.
