China's anti-waste campaign is being brought to the boil as central authorities issued a long and detailed circular calling on officials and the public to fight against widespread food waste.

The eight-point document, released by the General Office of the Communist Party of China Central Committee and the General Office of the State Council, is aimed to curb official extravagance at dinner tables and develop frugal diet habits among the public as well as make better use of leftovers and food materials.

With a large population and limited land resources, China has been facing a tight food supply-demand balance for a long period of time, but food waste remains rampant due to ostentatious lifestyles and lack of supervision, according to the circular.

The document outlines measures prohibiting too much money being spent on food among officials.

Officials are told to control the amount they spend on dinners in public affairs, and promote simple, healthy and economical dining.

Government departments, organizations and state-owned enterprises must publicize the amount they spend on dining for public supervision, according to the circular.

"Authorities are not allowed to organize banquets or guzzle under the name of convening meetings and training," it said.

China's anti-waste battle has been gathering steam since late 2012, when the new leadership announced "eight requirements" to improve Party work style and stamp out extravagance and bureaucracy.

The anti-waste campaign has impacted luxury food and gift industries in the past year.

A 2013 document ordered military soldiers to re-heat leftovers and keep away from fancy food.

In the latest circular, canteens and cafeteria of government departments were asked to provide "simple but healthy" food and put up "save the food" slogans in noticeable places.
