The article highlights the significant reduction in sweet potato cultivation in Binh Tan district, Vinh Long, Vietnam, from 14,000 hectares to just over 700 hectares, with the majority of the cultivation being purple sweet potatoes. The main reason for this decline is the loss of the market in China due to China's Zero Covid policy and the inability to export through official channels. This has led to a sharp decrease in the price of purple sweet potatoes, causing financial difficulties for farmers. The article emphasizes the need for official export solutions to increase prices and support the agricultural sector. The article also mentions efforts by the Vinh Long Department of Agriculture and Rural Development, along with other stakeholders, to secure export opportunities and address the challenges faced by the sector.
