US private equity group Kohlberg Kravis Roberts will acquire a 10% stake in Vietnam's Masan Consumer Corp. for US$159m, in what will be the largest ever private equity transaction in Vietnam, Masan Group said Wednesday.

The investment by KKR values the Vietnamese maker of consumer goods such as fish sauce and soya sauce at US$1.6bn, said Ho Chi Minh-listed conglomerate Masan Group, which owns an 86.8% stake in Masan Consumer.
