Some 4.2 million square kilometers were battered by this winter's strongest blizzard, which lasted from Tuesday to Thursday. According to the authorities, 92 counties and cities in northwestern and central regions have reported record snowfall for January.
The snow disrupted traffic, and damaged agricultural projects and some buildings, affecting more than 5.67 million people and causing a direct economic loss of 510 million yuan ($78.6 million), according to the Ministry of Civil Affairs.
The cold snap that swept in from the northwest brought heavy snow to central regions, mainly Henan and Shanxi provinces, over the weekend.
Residents in these regions have received warnings of a dramatic drop in temperature, including in the Hubei capital of Wuhan and the Anhui capital of Hefei, where the mercury is expected to drop by 10 degrees on Tuesday to reach record lows.
"After the cold snap ends, the low temperatures in the southern region will last until Saturday," Ma said.
The "bomb cyclone" that slammed the east coast of the US this month killed at least 16, according to CNN.
The US National Weather Service (NWS) said the temperature in New York City had reached an all-time low for January 6 of -13C (8F).
Thousands of flights from the city's John F Kennedy airport were delayed by blizzard conditions, and other airports in the eastern US also suffered problems.
More than 1ft (30cm) of snow blanketed parts of US states including Massachusetts, Connecticut, Maine and New Hampshire, according to the NWS.
In eastern Canada, temperatures close to -50C (-58F) were forecast for northern Ontario and Quebec. Toronto airport has also experienced delays and cancellations.
Some experts have suggested these storms may been connected.
The winter weather systems that cause snow and other phenomena in the Northern Hemisphere usually affect a certain region. For example, China is affected by the Siberian High, a massive collection of cold dry air that accumulates from September to April, Song Wenling, an expert from the National Climate Center, told China News Service on Sunday.
However, these systems are not separate because the hemisphere's atmospheric motion means they affect each other, she said, adding there may be some relation between the extremely cold weather.
