The annual event creates opportunities for local businesses to introduce their trademarks to consumers and consolidate the reputations of their brands.
As many as 250 pavilions showcase a wide range of agro-forestry and fishery products, handicraft products, jewellery, souvenirs, garments and textiles, and home appliances.
Renowned Vietnamese regional delicacies are also a major draw, including Dien Bien sticky rice, Uoc Le pork pie, Hoa Binh mushrooms, wine, and bee honey, Thai Nguyen tea, Buon Ma Thuot coffee, Ly Son garlic, and Tay Bac buffalo meat.
Fruit is another especially big seller as locals prepare for end of year festivities.
The fair kicked off at 07.00pm on January 18 at an exhibition centre, 489 Hoang Quoc Viet Street, Cau Giay precinct. It will last until January 28.
