China's National Development and Reform Commission has announced plans to stockpile pork to replenish state reserves, following a decrease in pork prices to below a warning level. The commission monitors a national average of pork prices against grain prices, which fell to 4.96 to 1 between Jan. 30 and Feb. 3, dropping below the warning level of 5 to 1. To prevent excessive fluctuations in hog prices, China has implemented a three-level early-warning system. The commission will now work with relevant departments to start the pork stockpiling process for state reserves and guide local governments to purchase pork.
