Within the Life Resorts portfolio, Minor Hotel Group has bought the 96-room Life Heritage Resort Hoi An and the 63-room Life Wellness Resort Quy Nhon.
The total investment amounts to $16m (£10.2m) for the two properties and acquisition of the brand.
Minor Hotel Group plans to rebrand both properties later this year to two of its existing brands.
The Hoi An property will be flagged under the group’s luxury Anantara brand and will become Anantara Hoi An Resort and the Quy Nhon property will be flagged AVANI, MHG’s new contemporary upscale brand, becoming AVANI Quy Nhon Resort & Spa.
Minor Hotel Group first entered Vietnam in 1998 through a joint venture in Harbour View Hotel, Hai Phong.
This was followed in 2011 by the launch of Anantara Mui Ne Resort & Spa on the country’s south east coast.
Minor Hotel Group chief executive Dillip Rajakarier said: "With the acquisition of these two resorts, we are proud to extend our hospitality offering wider in Vietnam, giving us the opportunity to welcome diverse travellers from the north to the south of the country and delivering the same service quality and hospitality as in all the hotels we either own or manage within Minor Hotel Group."
