The Ministry of Commerce of Thailand is urging local companies to participate in an auction to help farmers sell mangosteens faster and maintain an appropriate price level. The prices for different grades of mangosteens in Nakhon Si Thammarat Province range from 25-53.99 baht per kilogram. The Ministry is closely monitoring the price changes and negotiating with more companies to expedite the acquisition of mangosteens, while also warning operators to adhere to the law and prevent unfair treatment of farmers.
