In 2023, the agriculture and rural development sector will continue to promote the development of planting area codes for 20 hectares of peanuts in two communes Phuc Son and Minh Quang (Lam Binh) for export to the Chinese market.

The development of growing area codes in recent years not only helps traceability and ensures strict conditions for food safety, but also changes the mindset and awareness of people, businesses and cooperatives in organizing production. As a result, the province's key agricultural products gradually ensure food safety, meeting the requirements of domestic and foreign markets.
