The Chinese government has told families to keep daily necessities in stock in case of emergencies, after Covid-19 outbreaks and unusually heavy rains that caused a surge in vegetable prices raised concerns about supply shortages, reports Reuters.
The directive by the commerce ministry stirred some concern on domestic social media that it may have been triggered by heightened tensions with Taiwan.
In response, the Economic Daily, a Communist Party-backed newspaper, told netizens not to have "too much of an overactive imagination" and that the directive's purpose was to make sure citizens were not caught off guard if there was a lockdown in their area.
The ministry's statement late on Monday urged local authorities to do a good job in ensuring supply and stable prices, and to give early warnings of any supply problems.
The central government typically makes extra effort to boost the supply of fresh vegetables and pork in the run-up to China's most important holiday, the Lunar New Year, which will fall in early February next year.
But this year those efforts have become more urgent after extreme weather in early October destroyed crops in Shandong - the country's biggest vegetable growing region - and as outbreaks of Covid-19 cases stretching from the northwest to the northeast of the country threaten to disrupt food supplies.
Last week, the prices of cucumbers, spinach and broccoli had more than doubled from early October. Spinach was more expensive than some cuts of pork at 16.67 yuan ($2.60) per kilogramme, according to a vegetable price index in Shouguang, a key trading hub in Shandong.
Although prices have eased in recent days, economists expect a significant year-on-year increase in consumer price inflation for October, the first in five months.
The pandemic has brought an increased focus on food security for Beijing. The government is currently drafting a food security law and has also outlined new efforts to curb food waste after making the problem a priority last year.
The commerce ministry added that local authorities should purchase vegetables that can be stored well in advance and also look to strengthen emergency delivery networks to guarantee smooth and efficient distribution channels.
It added that information related to the prices and supply and demand of commodities should be released in a timely manner to stabilise the public's expectations.
China also plans to release vegetable reserves "at an appropriate time" to counter rising prices, according to a state TV report late on Monday.
It is not clear which vegetables China holds in reserves and how big those reserves are.
The state planning body has called for the timely replanting of vegetables, urging local governments to support fast-growing produce, according to the report.
Currently, China has about 100 million mu (6.7 million hectares) planted with vegetables, the agriculture ministry has said.
