Pepper prices in Vietnam's key growing areas have decreased by 1,000 - 4,000 VND/kg due to an increase in supply, with the average price now fluctuating between 136,000 - 140,000 VND/kg. This decrease is attributed to a surge in planting by gardeners and a reduction in demand from China. Despite this, experts believe that pepper prices will not decrease further due to the low global supply, especially in Vietnam which accounts for 40-50% of the world's supply. The decrease in prices is not solely due to reduced demand from China, but also an increase in short-term supply from people selling at high prices in May and June.
