World pepper prices on December 17 are stable with no new fluctuations, while Indonesia's domestic and international pepper prices continued to decrease. In contrast, domestic pepper prices in Vietnam increased dramatically compared to the previous day, reaching an average of 82,000 - 85,500 VND/kg. Concerns about reduced supply and a shortage of exports have led to the continuous skyrocketing of domestic pepper prices, with experts predicting long-term effects on pepper output and the position of Vietnam's pepper industry.
