Thai trade officials are monitoring the movement of cooking palm oil from Malaysia due to price differences between the two countries, with high Thai prices leading to smuggling. The retail price of palm oil in Thailand has increased due to dry weather and a rise in palm nut prices. Any movement of more than 25kg of palm oil in Thailand requires approval from provincial trade authorities, with potential fines and prison time for violations. The Thai Commerce Ministry is seeking cooperation from wholesalers and retail stores to maintain the retail price of bottled palm oil.
