The article explains the reason behind the significant increase in the price of coconuts in Vietnam, ranging from 150,000-200,000 VND/dozen. The high consumer demand, a decrease in domestic harvest, and export restriction policies from countries like Indonesia, Thailand, and the Philippines are the primary causes. The price can also vary based on the size of the coconuts and areas affected by saltwater intrusion. The off-season and a high demand from coconut processing companies for raw materials have led to a 50% decrease in output, further contributing to the high prices.
