The event aims to introduce Vietnamese products to Thai customers and balance bilateral trade.
Nearly 40 businesses are expected to sell products at more than 20 pavilions, mainly confectionary, beverage, tea, coffee, packaged food, spice, fruits and garment-textiles.
Vietnam and Thailand are implementing trade promotion programmes towards boosting two-way trade to US$20 billion by 2020.
Made-in-Vietnam goods are thought to have potential in the Thai market, notably fruits and dried fruits, spices and seafood.
The Ministry of Industry and Trade warned that Thailand has strict requirements on quality and food safety.
Therefore, to secure a firm foothold in the market, businesses need to improve product quality, reduce production costs and promote their goods.
The ministry suggested investing in packaging with full information on the products in Thai or English to attract customers.
The first Vietnamese Goods Week was held in Thailand in 2016 with almost 150,000 visitors.
