BEIJING - The People's Bank of China (PBOC), the central bank, on Thursday asked its local offices to ensure cash supplies amid persistent snow to meet demand for the Spring Festival, which falls on February 7.Snow has disrupted transportation, making it hard to deliver cash to the branches.The central bank, in a circular, urged its local offices to help commercial banks in getting or storing cash.The heavy snow that has fallen since mid-January, the worst in 50 years in much of China, has paralyzed transportation, frozen the power grid and caused serious economic losses.It showed no signs of abating as forecasters warned of three more days of snow and sleet.

SHANGHAI - One experimental clean-energy car runs on natural gas. Another uses ethanol distilled from corn. A third has a zero-emissions electric motor powered by a hydrogen fuel cell. Visitors walk around a Ryuga Mazda car on display during The Shanghai Auto Show in Shanghai April 21, 2007. These alternative vehicles were created not by a global automaker but by China's small but ambitious car companies, which displayed them Sunday alongside gasoline-powered sedans and sport utility vehicles at the start of the Shanghai Auto Show. At a time when they are still trying to establish themselves in international markets, Chinese automakers are already investing in such avant-garde research in a bid to win a foothold in the next generation of technology. "This is the tide of the industry. If you don't go with the tide, the industry will pass you by," said Qin Lihong, a vice president of China's biggest domestic automaker, Chery Auto Co., in an interview ahead of the show's opening. China's leaders are encouraging the development as part of efforts to cut pollution and rising dependence on imported oil and to make this country a creator of profitable technologies. Chinese manufacturers are getting help from foreign automakers in joint ventures and from research alliances with Chinese universities and government laboratories. Beijing has made cleaner cars a policy priority, targeting the field as one of 11 priority areas in a 15-year technology development plan issued in February 2006. It promised grants and tax breaks to support industry efforts. The campaign embodies one of Beijing's strategies in technology development: Pick new areas with no entrenched competitors so China can make breakthroughs without huge costs. While foreign automakers have a lead in conventional technology, "in new energy we're starting from almost the same line," said Chen Hong, the president of Shanghai Automotive Industries Corp. "So we believe we can catch up with other auto companies and make great progress in developing new energy vehicles," Chen said. China's leaders are pressing its auto, steel, manufacturing and other industries to improve energy efficiency and cut pollution. They see China's rising reliance on imported oil as a strategic weakness. China already is the world's No. 2 oil consumer after the United States and saw imports soar by 14.5 percent in 2006, driven by economic growth that has topped 10 percent for the past four years. A boom in car sales has added to smog shrouding China's major cities, which are among the world's dirtiest. Vehicle sales jumped 25.1 percent last year to 7.2 million units, including 3.8 million passenger cars. At the Shanghai show, both SAIC and Chery displayed experimental fuel-cell sedans, while they and a third Chinese automaker, Chang'an Automobile Group Co., also showed gasoline-electric hybrids. SAIC said it will start selling its hybrid next year, while Qin said Chery's would go on the market in two to three years. "The hybrid will be our focus," SAIC chairman Hu Maoyan said at a news conference. "The fuel cell will be our direction." SAIC has spent 100 million yuan ( million) on fuel cell research, according to state media. Chery had the widest array of alternative vehicles on display at the Shanghai show. They included models outfitted to run on bio-diesel made from vegetable oil or a "flexible fuel" choice of compressed natural gas or ethanol. Foreign automakers also are playing a role in China's research. General Motors Corp. has a joint-venture technology center with SAIC in Shanghai and operates three experimental fuel cell buses in the city. DaimlerChrysler AG has three of its own fuel cell buses running regular routes in Beijing in a research project with the technology ministry. Foreign automakers including GM, Ford Motor Co., BMW AG and Honda Motor Co. displayed their own hybrids and experimental fuel cell cars at the Shanghai show. Company officials said hydrogen fuel cells, which produce power with no exhaust, are the cleanest option. But they say it could be a decade or more before such technology is commercially feasible, due partly to the need to create a network of hydrogen filling stations. Chinese authorities also are looking at other possible fuels such as natural gas and methane extracted from coal, said Mei-Wei Cheng, the president of Ford's China operations. "This is not an easy decision, because every option has pros and cons," Cheng said. "The government is trying to find a solution as quickly as possible, but this is a difficult problem."

Beijing is bulging as its population has exceeded 17 million, only 1 million to go to reach the ceiling the city government has set for 2020.The figure breaks down into 12.04 million holders of Beijing "hukou", or household registration certificates, and 5.1 million floating population, sources with the Ministry of Public Security said at Monday's workshop on the country's management of migrants.Beijing municipal government announced last year it would limit its population to 18 million by 2020.Overpopulation is putting considerable pressure on the city's natural resources and environment. And experts have warned the current population, 17 million calculated at the end of June, is already 3 million more than Beijing's resources can feed.Given this year's baby boom, triggered by the superstitious belief that babies born in the Chinese year of the pig are lucky, analysts say there is little hope for an immediate slowdown in Beijing's population growth, even with the post-Beijing Olympics lull and soaring housing prices that have driven some Beijingers to boom towns in the neighboring Hebei Province and Tianjin Municipality.Migrants, especially surplus rural laborers who have taken up non-agricultural jobs in the city, have forcefully contributed to the population explosion in recent years.About 200 million migrants are working in cities across China.Last year, Ministry of Public Security proposed police authorities in the migrants' home province should send "resident police officers" to cities to help maintain public security at major migrant communities, many of which are slums that are prone to violence, robberies, drugs and gambling.Resident policemen are currently at work in three cities: Dongguan, a manufacturing center in Guangdong Province, Binzhou of the central Hunan Province and Guigang of the southern Guangxi Zhuang Autonomous Region.The ministry has also demanded all cities to complete a management information system of migrants' data by the end of 2009.

The head of the World Health Organization (WHO) Thursday warned of worsening health in the country's vast rural areas while praising the government for its commitment to improve healthcare in the countryside."The health indicators have failed to improve in pace with the economic indicators," said Margaret Chan when addressing a conference on rural primary healthcare in China."The health gap between rural and urban areas has grown even wider and health in parts of rural China is deteriorating."Medical costs are rising faster than the growth of per capita income in rural areas, she added.She said she appreciated the government's efforts and plans to build a medical system for all people, saying "when fair and accessible public health services become the clear targets of a country's public health policy, people's health will be improved".The WHO chief said she had noticed that the tasks on improving people's well-being in the report by Party chief Hu Jintao at the 17th National Congress of the Communist Party of China included a basic medical insurance system for urban dwellers and a cooperative medical care system in rural areas.She said recent WHO research has found that diseases are the source of poverty for 30 to 50 percent of the rural population of 737 million.A growing number of rural people, especially the aged, are suffering from various diseases; however, few have access to decent healthcare, she told the conference.Chan criticized the practice of allowing healthcare services to be commercialized in rural area, warning that it will cause the patients deeper suffering.The government has pledged to provide its population with basic medical care by 2020.It is expanding medical care through the Rural Cooperative Medical Scheme, a plan under which subscribers are funded to the tune of 50 yuan (.4) per person - 20 yuan (.6) from the central government, 20 yuan from the local government and 10 yuan (.3) from the individual.Vice-Minister of Health Chen Xiaohong said nearly 85 percent of the country's rural area, or 2,429 counties, are participating in the plan.

Beijing is planting trees and plants along riverbanks instead of covering them with concrete to fix its river system. It has taken almost 10 years for the capital to accept and use this idea. The ecosystems in the streams are gradually coming back to life because of the cleaner water, providing a good habitat for animals and plants, and ideal leisure sites for local residents.  Zhuanhe which connects with Kun Ming Lake in the Summer Palace is one of successful example of the river ecological treatment in Beijing. "In Beijing, there are 52 rivers with a total length of 520 kilometers inside the sixth ring road. Yongding and Jingmi rivers are the city's two main water sources, and Qinghe, Bahe, Tonghui and Liangshui are key drainage waterways," said Yu Kongjian, dean of the Sight Engineer Institute with Peking University. Originally, Beijing only wanted to control the floods by letting water flow out as soon as possible. Therefore, riverbanks were cemented down in order to prevent water leakage and the growth of plants, which could slow the water speed down. However, the shortage of rainfall in Beijing since 1999 showed that this method was not correct. On the one hand, streams had less fresh water to clean themselves. On the other, more polluted water was dumped into the rivers as more people moved into the capital. And in the summer of 2001, something bad happened. "The rivers in Beijing turned blue overnight and gave off a smelly odor," said Liu Peibin, vice engineer of Beijing Water Authority. There was an algae bloom due to so much pollution in the water. Algae covered the water surface and consumed most of the oxygen, and many creatures in the water died as a result. These "concrete pools" became the haven for swarms of mosquitoes which forced tens of thousands of residents nearby to close their windows and doors tightly especially in summer days. The water authorities had to act quickly for public safety. The first step was to demolish the concrete covering the riverbanks. The soil was exposed to water again, and the water could circulate down to the riverbank. Secondly, in order to stimulate oxygen in the streams, engineers put big stones in the water to create mini waterfalls. And they grew trees like willows and plants such as bulrush along the riverbanks. "Bulrush can purify polluted water through absorbing nitrogen and phosphorus in the water and exhaling oxygen," Deng added. "Gradually Zhuanhe came back to life and got rid of the polluted and smelly water. This would be impossible today if the brook was still covered in concrete." "What we did with Zhuanhe is a milestone in the progress of river treatment with new ecological ideas," said Deng Zhuozhi, vice engineer of Beijing Water Project Institute. He took charge of the Zhuanhe project. "How to fix up rivers depends on our attitude towards floods. We should learn to make friends with floods in a country where two-thirds of China's cities are short of water. Therefore we should reserve water as much as possible instead of discharging it ineffectively," said Yu.
