BEIJING — Pork prices in China edged down compared to a week ago, official data showed.

From July 18 to July 22, the average pork price tracked by the Ministry of Agriculture and Rural Affairs was 29.79 yuan (about $4.42) per kg, down 2.7 percent week-on-week.

The price was 38.4 percent higher than a year ago, narrowing 4.3 percentage points from the previous week.

China's hog supply in the second half of this year is guaranteed and hog prices will not grow continuously and substantially, Chen Guanghua, an official with the ministry said earlier this month.

The country's hog prices went up since late June and have seen a pullback recently.
