Tesco-Lotus, the Thailand unit of UK supermarket retailer Tesco, is to open a store in Roi Et in December as part of its "upcountry" expansion. Tesco-Lotus hope that the new store will encourage local community involvement to help the people of Roi Et meet their shopping needs. The company recently opened a new 34,224 sq m store at Bang Kapi, which brings the total number of Bangkok Tesco-Lotus outlets to 19. Costing Bt1bn (US$22.9m), the latest branch is Tesco-Lotus' biggest yet and will employ more than 420 staff.
