Indonesian retailer Matahari Putra Prima is to open two upscale supermarkets later this month and plans to open three more by the end of the year.

The two supermarkets, which will be operated under the Matahari Marketplace banner, will open in Serpong, a town outside Jakarta, and Makassar, the capital city of South Sulawesi.

"The Matahari Marketplace outlets will be opened in selected areas to regain our upper-middle class customers who have migrated to other high-end supermarkets," Danny Konjongian, a director at Matahari, told Dow Jones International News.

The openings form part of the retailer's plans to open six department stores and eight new supermarkets, including six Matahari Marketplace outlets, this year. The company is to spend a total of 360bn rupiah (US$42.6m) on the expansion.

Matahari, which has a 20% market share, opened its first Matahari Marketplace store last week in north Jakarta.
