A senior Communist Party official has ruled out the possibility of the mainland's rising food prices spilling to other sectors and leading to broader inflation. Zheng Xinli , vice-minister in charge of the ruling party's Central Policy Research Office, said the government's efforts to address the politically sensitive issue would start to take effect in coming months. 'Serious inflation will be out of the question because the rising pressure from prices has already been released in previous years in the process of our pricing system reform,' Mr Zheng said. The consumer price index (CPI), a major gauge of inflation, hit an 11-year record of 6.9 per cent last month, triggering fears that price pressures are spilling over from the dinner table to the broader economy. Food costs in November were 18.2 per cent more than a year earlier. A recent annual economic policymaking meeting has made the prevention of rising food prices from becoming widespread inflation a priority next year. Mr Zheng said the government's measures to increase food supply, especially pork, would greatly ease price rises, despite price fluctuations continuing in the short term. 'The government's recent policy measures will start to take effect in easing the price-rising pressure in the first half of next year,' he said. Mr Zheng said food price increases accounted for 88 per cent of the 4.1 per cent annual CPI rise in the first nine months, of which pork accounted for 50 per cent. He said the government hoped China's middle-income population would make up half the population by 2020. The National Bureau of Statistics has classified a household with a yearly income of between 60,000 yuan and 200,000 yuan as a middle-income family.
