Low temperatures and freezing rain in some parts of China also pushed up prices, the ministry said in a statement posted on its website.

During the week of 27 December to 2 January, the price of meat rose slightly, with pork prices up 0.8 per cent. Mutton prices rose 0.8 per cent and chicken prices rose 0.4 per cent.

Peanut and soybean oil prices increased 0.3 per cent. Colza oil prices edged 0.2 per cent higher.

Food prices have a one-third weighting in the calculation of China's consumer price index (CPI), the major gauge of inflation. China's CPI hit a 28-month high of 5.1 per cent in the year to November.
