"China Battles "Coldest Winter in 100 Years"

CHENZHOU, China - Millions remained stranded in China on Monday ahead of the biggest holiday of the year as parts of the country suffered their coldest winter in a century.

Freezing weather has killed scores of people and left travellers stranded before the Lunar New Year, or Spring Festival -- the only opportunity many people have for a holiday all year.

It has also brought China unwanted negative publicity six months before the Summer Olympics in Beijing.

President Hu Jintao chaired an emergency Politburo meeting on Sunday for the second time in a week to discuss rescue efforts.

"We have to be clear-minded that the inclement weather and severe disaster will continue to plague certain regions in the south," said a statement issued after Sunday's meeting. "Relief work will continue to face challenges, posing a tough task."

The China Meteorological Administration said the weather was the coldest in 100 years in central Hubei and Hunan provinces, going by the total number of consecutive days of average temperature less than 1 degree Celsius (33.8 degrees Fahrenheit).

But it expected brighter weather ahead, though fog could become a problem and temperatures at night would likely still be below freezing, slowing the thaw.

"It is still necessary to remain alert for possible low temperatures, frozen rain, snow, freezing and heavy fog," said administration head Zheng Guoguang.

He added the cold snap had caught the country off guard, in an area unprepared for such heavy snow. But climate change could see more extremes in weather in China, Zheng warned.

Four people died after a snow-laden roof collapsed at a fuel station in the eastern city of Nanjing on Sunday, Xinhua news agency said. One person was killed in a stampede at Guangzhou railway station in the south as people rushed to board trains.

Roads and railways, some of which have been blocked for days, have started to move again, and fewer flights were being cancelled, state media said, offering a glimmer of hope.
