The Plant Protection Department of the Ministry of Agriculture and Rural Development in Vietnam is gathering information from localities about the cultivation of citrus fruits such as grapefruit, oranges, tangerines, and lemons in the Mekong Delta region. This information is crucial for Vietnam to negotiate with China for the common opening of the market for these fruits. The department is seeking detailed information on the area, yield, and fruit output, as well as the farming processes and pest control methods used. The decision on which citrus trees to negotiate for export will be made after the information has been compiled. Currently, these fruits are not officially exported to China and are mainly consumed domestically.
